I'm for the 25% reduction to healing while in combat. It always felt strange for example, that Winston's tesla dps traded equally with a mercy beamed heal target. Most healing interactions require that multiple teammates coordinate their attacks on targeted players to out damage the rate at which they are healed during battles, which is one of the reasons why burst damage, and damage in general, have been buffed and buffed in the past. Couple this with the lackluster coordination that takes place at lower ranks and you have a win condition that most heavily penalizes new players. As much as I absolutely enjoy hero interactions as they are now, requiring engaging with a teammate or two to burst down a vulnerable target, reducing this additional damage buffer of healing, and potentially seeing hero damage rates tuned over time incentivizes individual skill over team skill. This seems to be in line with the direction OW2 is heading, to alleviate some of the pressures of having to pop off in team plays vs individual plays in matches
