A suggestion to balance Garen and make him more rewarding to play and play against
I think one of the big points of contention with laning against Garen is his burst on his Q and it's lack of counterplay and the inability to punish him with CC because of his W. Basically he Qs you E's away and goes back in when his Q is back up until he's whittled you away for an all-in ignite R kill.
I would suggest some kind of mechanic that rewards a Garen for staying on a single target with E.
Take some of the initial damage off of his Q and have it mark the target for increased magic damage on each tick of Garen's E if they are marked.
THe real downside to this change would be to make Garen's already linear kit even more linear with_ always _having to lead with Q
Just my opinion.
