Fair criticism. I do appreciate the QoL improvements. The Christmas period had a bunch of cool stuff, I nabbed a free Tatura and all. But I guess the negative things stand out more in my memory.
The telerian trials were out of touch. That event gave me the impression it was designed by someone who had run a bunch of stats on the backend but never actually opened the game on their mobile phone. That's before getting into the debate of whether the outcome was rigged to save face.
The artifact ascend advanced quest doesn't affect me personally, but if I was newbie around level 40 I'd be pretty pissed.
The design of both new dungeons is pretty broken. They're trivial to beat with very specific champs, but they ignore many of the basic game mechanics so a traditional team has no chance.
The awakening system is very kraken-oriented. The probability is quadratic (need drops of the same champ and soul, each very rare on its own). And the power level of awakening is concentrated in 5-6*, there are several blessings that do roughly nothing until you hit the high awakening bonus.
Plarium then replaced a bunch of tournament drops with low-value soul resources. They partially backpedalled on this after massive community backlash.
I distinctly remember the one tournament where they loudly advertised that you could win a tier 3 soulstone, which turned out to be a single one for the global winner.
And with all that said, the main problem of raid continues being the massive time requirement for actually completing stuff. The daily and advanced quests are all-or-nothing (the big rewards are locked behind getting all of them done). They have started addressing this very piecemeal (instant artifact upgrades, DT auto-climb), but the big, obvious time wastes are all still there. An hour per day on demon lord. A bunch of arbitrary quest requirements (use hydra key, arena with affinity, FW with rare), that has to be done each day. This is the opposite of fun, literally brainless clicking around. But it improves their engagement metrics, I guess...
ETA: I guess more than spender-oriented, I should have said metrics oriented. The stats on the server look good, while actual players are getting pissed.
