Rev Ultimate
It's very clear that the ultimate is strong especially in tandem with other ultimates of teammates ex: crypto, octane.. etc. I have no problems with that however the free use of abilities and ultimates in Rev form is definitely not fun to experience and I think many players would agree. All I would like to see as a change to Rev's ultimate, is that once you've taken the totem, you cannot perform ultimates. Again I will reiterate, No change in health, range, duration what's most frustrating is a team getting totem which audio destroys the game already, and other ultimate and abilities being stacked which causes more of the noise issues and a rather irritating way to try and get a team off you especially if your solo queuing.
If a team wants to push with a rev ult not letting them use they're other ultimates during the duration of a totem forces them to have to team play better instead of relentlessly pushing until you send them back to safety. They will have to use what they want to first cover ground or create an opening and save the Totem for last as a cleanup method instead of just free damage. Nerf to Caustic and buffs to Rev's effects to passives is going to create a power vacuum of legends a lot like we saw in the beginning of the game where most teams consisted of the same 3 characters. If you haven't play tested these effects, and don't understand your legends from a competitive standpoint is going to effect the casual player base as well.
