Every type must have its unique weapon or you just gonna have 3 same mechs just in different colors. About mods use and weight.. i can agree on weight that its to big for this type, but about mods its 50/50, again mech types dont must use things in SAME WAY, energy always had opportunity of glass cannon builds, minimal hp/max res and high caps with minimal reg/cool and you know? its works. Not so many players use it but its works, especially in 1vs1. So stop make from everything "double shotgun"
