Beyond upgrade slots for mods, shield regeneration and shield strength, is there any actual benefit for upgrading these suits?
I can pretty much steamroll over every CZ and Mission so far in just the basic, nonupgraded gear.
I think the issue will be PVP, where one CMDR in G5 everything becomes an unkillable slayer.
I would suggest CZ be restricted to certain engineering levels. E.g. Low Rez CZ = max G1 gear, Medium = G3, High = anything goes.
Since we can apparently have multiple suits, it wouldn't restrict anyone from going to a CZ for a PVP session - they'd just have to slip into something more suitable first.
