It's 2015 and Riven, Katarina, Garen still dont have a resource bar
There is absolutely no point for a champion to have no resources to manage.
you can say whatever you want, Riven has long CD, Katarina is based on spells Cd, whatever, it doesn't make any sense.
I belive they didn't want to give Garen a resource bar couse he is a champion for new players, so something easy to pick up and play. Do you think Riot that new players are completely retarded or what? Managing your abilities and your resources is like the first thing you have to learn about this game, and it's not something super complex to learn... You can make this champion so much more interesting then this.
Riven is a champion that not only is incredibly snowbally ( and unhealthy), but honestly she has 0 reasons to not have a energy bar, a mana bar, a fury bar, a chocolate bar, WHATEVER. Just balance her around a resource bar, if the only thing limiting your ability to harrass an enemy is to wait 5 seconds, what's the point. Try to play a Malphite toplane, and you will see how hard is to manage your mana bar to stay long enough in the lane, Riven not only has a kti that permits her to win basically anytrade at ealry levels, but she can do that ENDLESSLY without a mana bar.
Katarina is the only one that i can understand, more or less, but i still think that it's unhealthy in general for the game. Someone limited by a resource vs someone who has no limits is never an equal thing. I think Katarina should have an energy bar, with mechanics to gain energy doing your combo and stuff, so that you can do all the fun things you did before, but being smart about it, otherwise if you fail you have to wait your energy to refill.
and especially
up to him.
to name a few.
