I usually am not a try-hard player. I do not try "stupid stuff." I play to win, but TAW allows me to focus on 1 type of effort - 1 lane, eco, air, raiding, water, mobile support, expensive support, nuke/widow, super weapon construction, etc. I can also switch focus as the game evolves. I do not need to do all those tasks at once in a TAW that I would need to do in smaller teams or 1v1.
I play to relax, but I like the competition of large TAW games. Often, I just like to watch TAW games because the victor usually is not decided in the first 5 minutes like most 1v1 games and recovery from a losing position is more likely in a TAW than a smaller game due to super weapons. If I cannot play a TAW because there is no room, then I often am quite content to watch.
It feels great to use Nukes, Odin, Scylla, Tac Nuke, DRP, Zenith, or Sneaky Air Strike, to turn a game around - or solidify a winning position.
My profession is mentally very taxing so that is not what I want from a game.
