ignite is unnecessary if you play ww well, you go ap tank so u are harrassing with q and then run again and keep on, if you know u can kill enemy if they cant run to their turret or any situations like that run use q and then ur ulti remember to pop w and have e ready ALWAYS (exept for when ganking and enemy on low hp) also ghost is a nice initiating way, you can turn ghost on, if enemy under 50% hp yummy speed boost cause of your e and then pop ur ulti if they are way too far also ghost will help ur champion alot early game with killing AND escaping you can change ghost to flash but i would prefer ghost (in ranked look at their team and choose wisely!)

I agree with u, But you should think about the way he is and why he needs to be ap/tanker. Also when the team needs someone which is ap or a tanker. And i will not prefer ghost to him rather ignite because he got his (E) spell and all knows that Warwick can easily get the enemy team to under 50%

Instead of going so much ap i would focus more on a more tanky build for ww... but also i would prefer a ww with some anti tank in him... like madredz bloodrazors i know they aren't ap item but it can be a great boost for him maybe throw out zhonyas or rabadon and change the seals to mana regen/lvl x9 and also cdr/lvl glyphs else it looks good at runes, now for the summoner spells i would rather have ghost instead of ignite and i would never take exhaust because with ww's insane life steal and his damage in q and ulti (also his w is a nice boost) then enemy should easily come below 50% hp if not already then your blood scent will let you run away (Yay!) also if ur against heavy ad team like xin, garen, corki, lux and veigar (veigar and lux not ad but its just like a team could be) i would go for the first tanky item which i think should be sunfirecape or randuin's omen then i would focus on rushing banshee and change my boots to mercury threads also teleport is a rly bad choice for a tanky ap ww cause he isnt ment to backdoor now to masteries... i would go 0/21/9 instead because i would focus more for the tanky part but ONE LAST NOTE: i wouldnt say the quintessence is good for ww with flat ap because its only like 15 ap *Cry* well althrought it looks fine and i will try it once :) Voting down, i dont see that much in it like cons or pro's
