I def see the higher point requirements and the different points of view on how hard or easy fusions should be.
Has anyone looked into the fact we now have an easier time clearing points per run? Spider h10, Dragon h10 and IG h10 are fast, as fast or faster than my 25 in most of those, the same energy cost as normal 25, and drops vastly better gear. This means I get more points per click I make on my phone and time I work in to run dungeons.
With the release of the Hard Dungeons, I wouldn't expect costs of fusions to remain the same. Even if there is slightly more efficient or same energy/run farming at n20, the time issue is real. The cost of my time in completion of a fusion is part of the reason I might would need to buy a pack or drop many shards in the bonus summon rush.
Like Angwil I do a lot to all of my fusions on mobile, and h10 on super raids is such a nicer way to do it than a year+ ago on Normal 20 only. Fusions like Brogni were a true grind, and exponentially harder than this higher than previous (yet longer) divers. That and Karato are still, for me at least, the toughest fusions. Both were hybrids like this, both required a ton of resources for me at the time, and both had zero room for error and no extra bonus events out there really.
