1. With the elite and legendary packages will the extra mech slots be available after the premium membership runs out?
2. Can I buy 2 elite packages to double up on it's features ie, 2 founders mechs, 4 months premium membership and $160 in-game cash?
1. The extra founder slot are linked to the founder mech not to the premium. So they will stay forever.
2. No info on this but I really believe that this is not possible. Since allowing that will reduce (and quite a lot) the real value of the Legendary packs!
