My friends and I loved PRO before the update. Since they added the new EXP System we stopped playing because we're taking ages leveling up our pokes and somehow our lvl. 70 Pokemon get easily killed by lvl. 50 mons? How? We don't have so much time so we play in the evening for an hour or two but now we had just sessions where stayed in one route and try to gain exp somehow.
I don't know its just not it... Since then we left PRO for now even though we purchased a lot of items in the shop and the Membership to get more Exp... well that goes out the window now.
I say revert it back to the original leveling system.
