Firstly Raid is a great add to the game and is a nice game mode that everyone can have a go at.
Thoughts on game play:
They do seem a bit like regular missions and not too much strategy beyond killing them while taking minimal damage. This means getting the energy to 0 in 1 hit or getting them double overheated. This massively disadvantages physical mechs (me) which is not a problem apart from it seems this can be done on every raid mission!
It would be nice to see raids themed a bit more each day. So that on some days it would be impossible to overheat the mech or impossible to take the energy down to 0 on turn 1. (max values at 600 with regen/cooling at 200ish)
I would say that the HP of the last raid should be a lot more. It seems a shame that several people got 1st but only 1 gets the rewards. If its made slightly harder hopefully this wont happen.
