If only, LMAO. Beams will be interesting none the less,
I don’t think beams will be able to clash with beams because of them being hitscan, if not near hitscan.
However, like explosions (I think?) they would probably be able to clash with a blast.
Clashing is probably just gonna be “whoever has the more advantageous beam wins” just like the blasts 
Suddenly, mashing minigame.
Ok the minigame from arcane was pretty fun to me at least and it spiced up combat, if that was re-added(which I highly doubt would ever happen) I’d think that it would be fun.
Idk how they will clash
I think the mini-bosses use the beam attack sometime, pretty similar to shooting 20 blast attack in a single line
