First of all, it seems like the pocket pistol's and the Atomizer's unbanning went well so I think the rest of the leagues should consider also unbanning them (maybe it's not the case but I'm not seeing anyone complaining).
Second of all, as wish has mentioned about the Vaccinator, unless the medic is killed at the start of the push, the defending team would have a resistance from a source of damage and every 6 seconds they’ll get an even higher resistance for 2.5 seconds which makes them almost unkillable (although from my perspective it’s pure theory crafting, it seems like it’s already hard to kill people after the Uberfight).
Lastly, would class limits also be tested? From Ozfortress and ETF2L it seems like 2 Snipers and 2 spies did not hurt the game and even if it’s not that viable to run 2 spies or 2 snipers, it should be considered to change the limits to be more open because it seems like Valve don’t want accept the heavy class and weapon limits so loosening them a bit would surely be helpful right? Also I understand why heavy, Engineer, and medic are restricted to 1 but may someone please explain the other restrictions?
