Nicknamed "The Missing Link", Gnar has often felt like he's been missing something in his kit. Sure, when you pull off the Mega Gnar combo after throwing a boulder and tossing three of your enemies into the wall, it feels great. But what happens after that? You most likely just peel backward a bit while soaking in all the damage before you transform back to Mini Gnar. It's a cycle that often makes you feel unsatisfied.
As it stands, Gnar is one of the least popular top laners due to his underwhelming kit. As Mini Gnar, you simply don't do enough damage and as Mega Gnar, as we alluded to earlier, has a very "one-trick" feeling after you execute his combo.
According to champion.gg, Gnar is the fourth least successful top laner with his 46.26% win rate. People, however, still have faith in him as his play rate is in the middle of the pack with a 2.04% mark.
The numbers tell even more stories. His 4.86 kills per game are very low for a top laner (Quinn and Talon lead the way with eight or more kills a game). The argument could then be made that he's more so a tank and he isn't supposed to get kills. Well, the numbers debunk that immediately. His 28644 damage taken per game is barely in the top half of that category as he's not predominately a tank. He's a hybrid build, and a tricky one at that.
According to Meddler, League of Legends Lead Gameplay Designer, changes are coming for Gnar (both Mini and Mega) in the next patch, 7.6.
Somebody on the forum posted the question, "Hi Meddler any plans for Gnar? He seems rather weak, even with the tanks that show up on toplane that he is supposed to be good against."
Meddler then responded with, "We've got a couple of small Gnar buffs in 7.6. Looks like those might not have been datamined given his passive and base stats are set up in an unusual way. Short version is more HP regen for Mini Gnar, somewhat less for Mega Gnar, which should overall be a laning phase buff, especially when Gnar's behind. Spell queueing mid Crunch should also work properly too now, rather than requiring a cast after landing."
