we have missiles in the game overwatch ultimates etc etc
The gunplay is still technically a tactical shooter, but recently, more new characters have had ults that provide wide status effects across a portion of the map. So, I wouldn't say it is becoming less tactical shooter-like but rather more ability-focused, such as Overwatch. However, this game has had abilities that have done this type of thing since launch, it just seems that they have been adding more in a quick time frame. I think the real problem is that ults are too easy to farm and combining them can sometimes guarantee rounds if you play them right.
