Sure no problem bring your mech into the SM Moshpit and I'll kill you real good!!
Only main good thing I liked about a bunch of the legacy weapons was they didn't need ELE (electric) so the ELE bots couldn't wipe out all my weapons ability to work.
Like now the new weapons that have no elec needs are very rare.
I do like and still use my Legacy Mythical Lavaspray Mark II until I get the new version anyway.
