Laser is primarily for moving, it is mainly a tool..a over-powered one at that, it isn't taken away from you completely, combo's fair enough, but same could be said for nex + mortar combo..you need to get both guns before you can do it.
Anyway, franco has designed the map like that, I will have another play on deck tomorrow, and with this feedback and that match go from there.
If so then it will only be one map, but franco has stated the reason why not to include it as a starting weapon.
I have played that map of his without it, and I have no problems, plenty of ways to get up high and there is mortar/electro jumps also if you dont have laser.
