your telling me... I have all LVL8 walls.. the black ones. To upgrade to LVL 9 they are 1Million each.. lol
Took me 5 weeks to upgrade all 225 pieces to lvl 8... And that is all i spend money on the entire time.. and i was 10 times a day...
I think he means upgraded his Th few levels before maxing out his base at his current th level... Makes for Others much stronger players to easily raid his base.. and also for him to only be able to attack much stronger opponents.
