have YOU ever actually played AD Sion?
you have more movement speed then 95% of all champions so there is no problem getting close. his AD is high enough to 3-5 shot tanks and his stun ability just makes it easier. you can easily get over 300 AD with only half the items.
who to pick? AD sion, jarvan, Yi or Xin Zhao....
that all depends on your personal preferences. they are all viable.
Why yes, I have.
315 base movement speed is below average for a melee dps, and not, as you say: faster than 95% of champions.
His AD is not high enough at all to 3-5 shot tanks. At level six if he is maxing enrage first he still only has 120 attack damage. By comparison, a Maokai with no runes or items still has 953 HP and 42 armor. If you are killing tanks in five attacks they are doing something wrong.
Who to pick? Well, if I know one thing, I do know that Jarvan is getting constant nerfs and is still picked at a high level, Xin Zhao is consistently picked, Yi is a viable jungler, and I have never seen a single AD Sion on any high level stream or tournament.
that the the theory. fact is that most of the time you either don't need to or can't do it all due to the fact that either they can get passed you or your team nukes hard etc etc.
also, i can do those same things with Xin Zhao with 2/3 items. it all depends on team play and team composition.
there is a reason Leona's abilities stack from AP, maybe cuz of the fact that they give you the opportunity to go AP????? (else they mightve just deleted that and just give her base damage a huge boost eveytime you upgrade something so you can stick to buying tanking and support items)
atm there is no such thing as a full tank champion. even though they want one, thus creating leona, there still isn't one. they can all be played AP or AD and be viable.
If the enemy is getting past you as a tank, you aren't playing right. All teams need the ability to initiate and the ability to peel attackers off their carries. If you don't have that on your team you are going to be at a massive disadvantage.
No, you can't do those same things with Xin Zhao. Perhaps release week Xin Zhao, but these days Xin Zhao is very squishy, and needs to build damage items. If you try to initiate against a competent team you will be stunned, exhausted, and blown up.
Yes, there is a reason Leona has AP ratios, this is because every single character has abilities that scale with something. No character has no scaling abilities, but just because a character can scale with a stat doesn't make it a good idea to buy that stat. You don't see many Amumus going AP, do you? Well he has better AP ratios than Leona.
No, you are wrong. There are full tank champions, and playing them as anything else is the wrong way to do it. Shen is not viable built anything but as a tank, neither is Rammus. Malphite is only built as a tank.
Please, stop exaggerating so much.
Teemo is proper fun building as a tank, since mostly the AD carries focus you and you have blinding darts and shrooms to kite them around while their team follows with your team slaughtering them on the way. he isnt a real tank ofcourse but can be build quite tanky (know a troll post when you see one kkthnx).
obviously you havent seen an AD kata with 2 warmogs sunfire cape force a nature, banshee's and atma's. it takes along time till you kill her and in the mean time you focus her because if the damage she puts out, your team dies of her ultimate and her team ^^ thus making this quite interesting.
pantheon is pretty amazing, good initiate + stun. his passive + stun's passive makes his defense pretty good with an defensive build and defensive items.
although i prefer him as damage, like most people do, i do quite enjoy tanky pantheon from time to time (ever tried it? doubt it.)
That may be, but none of these characters are actually viable built as a tank. A team has absolutely no reason to focus a Teemo when he is doing no damage. Yes, obviously I have never seen a Katarina build that, considering you would need 16,290 gold for that build, which, may I note does not include any boots. This build would also only give her 220 attack damage. Hardly damage to run from. Crit and mana are also wasted stats on Katarina. Pantheon built as a tank? No, of course I haven't tried it, I don't want to ruin my teams game, once again, if he is built as a tank the enemy team has absolutely no reason to focus him, he will do no damage, his stun is almost on a ten second cooldown, his ultimate is terrible for initiating past the laning phase.
my enemies weren't bad. actually quite decent as our team was losing, but the AoE stun and burst damage was too high for them to handle, doubt anyone in their shoes wouldve done a better job.
i am certainly not "laughing off" your opinion about how to play a champion.
i am merely proving you wrong. if leona has such horrible AP ratios(is true but damage is still retarded) and shouldn't be played AP, how come i can still quadra kill an enemy team, which weren't even bad players really, and get such scores?
imho, it's all a matter of opinion to be honest and how you like to play.
If Leona's of all characters burst damage was too high for them to handle, I would hate to see them play against a Brand, Annie, or Malzahar.
How can you quadra kill the enemy as AP Leona? They didn't know how to play against a new champion, and were simply bad. The only way someone with such horrible AP ratios could do so well is if they made a multitude of bad decisions and mistakes.
It isn't a matter of opinion. You don't build AP Rammus because it is terrible, likewise, you shouldn't build AP Leona.
