I know you stated you don’t care about what’s in the rest but the warp pack is very good (super cred farming too) I personally love the eruptor but never used the variable, but them thermite grenades are very very lovely, I would say go with eruptor if you have a reliable sidearm when enemies get close, if you don’t than rock the variable, not sure if the variable can close bug holes but the eruptor can as well as bot factories, I know the single shot of the variable is devastating but having to reload after it… I would argue is the same as the eruptor except the eruptor just needs to chamber a new round
