Champs who could use some buffs/reworks

Aatrox- this is an interesting idea as a lifesteal based top laner, but it doesnt feel like he lifesteals better than anyone else and while his passive is ok and his q is actually good his w is just lackluster, his e is a difficult to hit low damage low slow useless ability. His ult is interesting but useless, the range increase is ok but why does it have no ad booster or even an ad ratio? the beginning burst is all ap scaled and it makes no sense.

Olaf- This guy needs an almost total rehaul- the ult with bonus ad and cc immunity is cool. The q is ok and possibly keepable but the rest is either useless or op. His passive is absolutely useless, and all his sustain is entirely dependent on his w which would be good if it wasnt ignorable by anyone with any burst or grevious wounds. his e has some nice burst but overall i mean come on a burst that hurts you.

Yorick- the idea behind a minion summoner champs is very cool, but hes based so much just on e to sustain and then button mashing. he needs to be changed from a fighter top lane with minion spam to a support tank minion summoning based character that requires usage of minions for most everything. his q is ok where its at i guess, its a bit lackluster on damage though. his w needs more slow burst for playability. His e needs to be more of a poke with ok sustain and a reduced mana cost. His ult would be fine where its at if it was made to be what the tooltip says but as of now it spawns no revenant until they die and even then sometimes it just appears not to work even when the ult goes on cooldown

Taric- What is this guy anymore. his passive is ok with armor reduction and ability cd reduction. His q is just a heal that doesnt feel like it does anything at all, needs a armor scale. his w needs to have the active removed, it makes no sense that a tank support would sacrifice armor for damage, if you want to keep the passive he needs the armor reduction after dumped. his e is ok if you added some missile speed and instead of doing a duration change based on range just be a flat ratio, also armor scale. His ult makes no sense, why do you have an aoe damage ability on a tank support as an ult. just make it an aura with ad and ap boost

In any case tell me what you think
