Thanks for the advice guys, I will send the other units to the barracks and focus on lvling my main team with all youre advices

@buttlover - oh well Im not planing to spend cash in the game for a while so the mincost can wait lol but I might spend $ for the last SC for the 150 stamp card (no way Im spending for the 250 one)

Oh and for the record (to te unregistered user) Im not planing to ditch my silvers yet, I have 4 teams (my new one with the new units, the old one with the silvers, one of only ranged/woman and one of only men, I switch em as I need em) but once I find a balance or get strong enough its quite sure that they will either go to the bench or will be used for awakening
