I really gotta disagree here. Considering that they reduced the number of available frags by 5, it's absolutely brutal.
Do I think the requirements are too high generally? Yes. But like I say I was surprised they hadn't gone higher. I class myself as now mid to end game and other than some shard luck for summon rush this fusion has been easy to complete. The only real annoyance could have been if I had to do the two dungeon divers but I've managed to ignore them thanks to CB drops.
