I'm having trouble understanding all the chatter regarding the difficulty of this fusion. Granted, we have not seen everything yet, but;
1) so much chatter about 9350 pts on the training event? Really? Have you been around a month? This is the same requirement for last months Ukko frags and for many others fusion/frag events as well.
2) you can get the epic and completely skip 4 of the other events entirely. That does not happen in frag events. The trade off is having to level/rank/ascend the champs. Which you can easily do for the most part while completing the training Tourny.
3) you can easily collect 8 to 11 of the rares, and the epic, before the training tournament is over. Upgrade 11 rares and 3 epics to get the 12th rare. Skip the chase, spider, diver's 3 ,and enhancement 3 entirely. or you could skip some of the others and complete some of the last ones knowing you'll need to upgrade without the training Tourny going on.
if the champ doesn't inspire you, that's a different question. But I'm not seeing how difficulty is a reason to pass on this one.
