I actually found out and started the game a couple days late, so I missed out on the Bloom Dragons and was stuck level-capping EACH AND EVERY SINGLE ONE of my bases and feeding them gifts from a machine gun (gawddam, they are freak'n cake monsters and jewelry thieves OTL). Now that I can access the Bloom Dragons and thanks to the time spent on gift gathering, my Helper-total almost shot up 5000 points upon evolution, instead of decreasing. My overall total also shot up about 20,000, from 170k -> 190k, after boosting them back up to Lv25; this was all done today with the Red Bloom Dragon and I still have 3 more to collect.
