I know you said that you want specific changes, but some of the nerfs we need the most I don’t really know for sure how to handle. I know that right now, with the exception of montana, tanks in general are VERY unabalanced, and that includes those that are “tanky”, but not necessarily tanks.
I think like someone said above, boldur needs some cooldown rework for starters. It takes a while for boldur’s damage to become an issue, but with a tank it should never become an issue. Beyond that, and most importantly, think about how easily montana is countered. There are so many ways to keep him in line. It requires coordination from his team to really push with montana. Boldur is so far from montana. Having to hard cc someone 8x to kill him is way too much, when I can solo kill a montana with freaking whiskey foxtrot, but not with his team doing their jobs. Boldur is entirely different. I think a major cooldown reduction would be a great start. I think they also need to just flat out drastically slow him down.
I think that kelvin’s stun needs a major rework. It is far too easy to use with far too great of a payoff. Again, compare him to montana. Montana has to make very wise decisions about going in, and Montana is ALWAYS at risk due to his size and speed. Kelvin just hits a button and stuns the whole team while being able to safely return to his team. I think cooldown and actual time the skill is active need to be changed. I think it should be changed from a stun to a severe slow as well. Perhaps something like miko’s late game slow, but not right away. He actually needs reworked rather than tweaked.
I think galilea is probably the second character most in need of a rework, only to beatrix which i will address in a moment. Galilea needs to have her stun removed. That’s right, I said it. If she is a territorial brawler, and has a pull, has a silence, I guess that all kind of fits into the description. Those things need to change in some way, but the stun needs to go. And this is from someone who plays her very frequently. It does not fit into her kit or her role. Being stunned, then pulled and silenced by one character is far too much. Remove the stun.
Beatrix needs to either be removed from the game, or have the silence removed from her helix altogether. There is no way to rework that silence to be balanced if it remains something that can be done from across the map, which that skill will always be able to do. The only possible solution is to make it single target only.
Melka needs to be brought back to where she was before any of the nerfs. She was strong, she was fine. They have slowly been killing of characters that could remotely handle tanks, one by one. She was actually one of the closest things to an actual counter to boldur. The only actual counter to boldur the game has ever had was ghault’s old trap, into an alani bubble, into a gali pull, into a gali stun. Then you might kill him.
El dragon needs his time back on his stun and his survivability back. I think the change in the size of his ult is fine, but the rest was overkill.
I’ve given orendi a lot of thought, and I simply do not think you can nerf her until you have nerfed everyone else that needs it. She is basically the only thing that gives a team hope other than just strong tank play, and that is getting really boring. Tanks have to change.
