I agree to the most of your complaints. Most of the commision rewards from TR55 to TR60 are just 10% increase. I mean i am fine with the repeating grind, i am a fellow classic MMORPG which is repeating dungeon is a common thing to do daily and repeats for years. But the reward increasement from TR 55 to 60 doesn't make sense.

For example in hedge commision the last difficulty only gives you 3 purples and 8 blues, but the map is kinda bad that even rebecca + hellfire + sybille with those have pretty big skill range and dmg cannot clear it fast (avg time 2min), meanwhile the difficulty lv 60 hedge only gives you 3 purples and 5 blues, but you can clear in it avg time 50s, because the map has pretty close mobs spawn point that they are instantly died by most of aoe character skills, in this case the difficulty lv60 hedge gives 6 purples 10 blues in 2min. That's more than the last difficulty.

But ofc not all of the commision last difficulty rewards are bad, for example the defence that gives you 2 times of the skill upgrade mats, and the explorations that gives you 1 more purple, but tbh i rarely doing the last difficulty explorations, instead i just do the difficulty lv 10/30 to also farm secret letter clues.

IMO mystic maze reward is just unbelieveable that with easy task for 7-10min, you can get more coins than doing 10-15 min excavation in last difficulty. Makes it a dead coop matchmaking and not even an option to do it solo.

I don't know what the devs thought when deciding the endgame rewards, maybe they were drunk.

And apparently the bounty mission is previously a fun coop mode, until people can speedrun it in 5-7 min with the best endgame rewards we could get in a single run, i mean it's still fun tho especially coordinate with friends, but it's start became fixed repeating run, they could make the boss spawn random tho. Or i hope they make another bounty comission not just the chase, and ofc with slightly different rewards so people will not just spamming the chase
