garen needs the warwick treatment.
just improvements all around that keep him the same at his basis, while building some advanced mechancis into his kit.
and no, it cant wait another year or two. hes an 8 year old champion, who has been at the bottom of the competitive viability for his entire existence.
and for crying out loud, give him some way to stay in a fight. his w active doesnt cut it. he needs some actual in combat health sustain or some other way to deal consistent sustained damage, like every other fighter and carry in this game.
otherwise hell just keep being able to fight for 5 seconds to get subsequently destroyed in the next 9 to 5 seconds when his spin is on cooldown, for the rest of his existence.
he doesnt have
or
mobility to disengage a fight and work around his own cooldown windows, and even those guys have viable sustain items to trade auto attacks.
is still a beginner champ, and they managed to put some outplay tools into his kit.
shield,
turtle stance spam,
missing health heals,
lifesteal... you can go down the entire list of fighters and they all have ways to deal uninterrupted sustained damage, while being able to negate incoming damage either by healing or shielding (not just mitigate it).
(pre-rework) and
. so theres that.
can extend past his auto attack range by sending his ghouls.
his cleavers. other strict melee ranged champions have higher mobility to compensate.
like
is one of very few exceptions of fighters who is at the same time not very mobile, and entirely restricted to melee range in his entire kit. and hes not a good jungler like
to be able to avoid matchups where he gets outmaneuvered and outpoked, which is basically every matchup.
or something like that.

e. just a flat damage increase off crit chance and crit damage. otherwise it would create too much variance in the abilities damage.
