In the mechlab you could select an "era" for the mech you want to customize, e.g. 3025.
Obviously it could be selectable only for mechs avaliable in the timeline for that era (so the option would be grayed out for clan mechs).
You can use tech only for that era (e.g. no DHS, no XL engine, no ER lasers, no clan tech, etc).
If you select QP you will be grouped only with mech of the same era.
Pro: more variety to the game, with variants that could be "not upgraded" for this kind of matches.
Cons: QP queue will be split up for each eras introduced.
Thoughts?
