I want to discuss three potential A class heroes, who just can´t shine because of their skills charingtime.
Chesterfield: If you get his skills set up he is a killer. He can do 200k damage with two bullets. But it is hard to get his skills aline. The cooldown of bear trap is so high you only get to use it once or twice a match. And without his set up he is just okay. Also his shotgun has such a long reload, that you can´t really do damage with them. Even if you hit both bullets, the damage is easily healed untill he reloaded.
Ghoul: His skills are just amazing. Up to 300k Chem area damage, but save 100k with his Silver. 12 second skill block with his Bronze and self healing with his Platinum. The only Problem is that no one runs into his skills. How often have you seen someone running into his bomb? There is only one active, because the first one explodes on his own, before the second one gets casted. How great and how much more tactics would be introduced, if he could have two or three or more bombs active at the same time. you could nail down an opponent behind one cover and after it is destroyed he has to decide if he takes the damage of the bomb or if he stands there coverless and taking the damage, hoping a heal safes him.
The cooldown of his Silver should be lowered to 20 seconds and several should be active at the same time. Take away the timer and limit it to three active bombs.
Scum: I only have him on Bronze, but his Bronze skill has an overly long cooldown. It is said in his description, that he dominates the battlefield by making the opponents change positions constantly. But in reality you have to be quite stupid do be hit by his Silver or to really get damaged by the side effect of his Bronze. If he could cast his Bronze faster and if the poison cloud stays longer, there would be more of his poison clouds active, so you have to look out for them or even have to step into one, because there is no free spot without. Anotehr possibillity would be, that the poison cloud wafts around the battlefield, untill it hits an opponent and is dealing damage per second then.
These are all just small changes, which would lead have a big effect on these heroes. It could change gameplay, If bombs, traps and poison clouds would be a real threat. Right now a damage dealer spams his skills or clip and then hides and changes cover to spam it again after recharge. Same with Healers. I can´t count how many times I have seen Flatline running around to save her, just to use her revive. This would be gone, or at least reduced. You can still do this, but you could run into a trap. Take Caine or Dogface as an example. They want to hide, but their cover is gone. The next cover has Ghouls bomb behind it. You have to decide if you stay coverless, or take the 100k to 300k Chem damage, which could lead to an instant kill. Or Salvatore is firing his skill at him and you qucly have to decide which skill does less damage. Ghouls Bomb or Salvatores Heavy Artillery. A mech should take the neutral damage of Salvatore, but an energy should move and take the bomb damage. But would you always take the right decision, if you have barely a second untill you get hit?
To get even more tactics into the matches, it would be awsome, if you could throw bombs or skills like Mavens Vampiric Cloud freely behind covers and not only at heroes. You could block covers with that nailing opponents at certain positions. Or you could throw Moss healing cloud to the cover next to him, if he is standing inside a poison cloud, so he could move out and get healed.
