1. Less than calamity 5-6 and it's waste of time crystal wise

2. Insanely many 1-shot mechanics. One bad rng with positioning and bam, need restart all over whole fight

3. You need to run to bosses all over map. 

4. Crystals are rng. I cleared 5x 5-Calamity and got nothing in return. It's like doing world bosses basically..

6. BDO devs are so dumb they put lowbie crystals as bottlenecks for craft. so 3k preorders or wait to buy for 300mil and gain no profit

It's for people who want some pve challenge, but reward wise? Meh rather go grind and waste stack of 100% loot scrolls.

Sad part it aint even a challenge, objects hinder your movement, aoe overlapping, audio-video-text indicators don't align very often with what really happens, rng not only with mechanics but your own iframes. Bosses just do more dmg and are bigger bullet sponges, imo fights are too long as well.

Rebuffing pain in the ass, w8ing for cooldowns sucks too.

Timeout deaths are braindead since we have leaderboards for fastest clears.

Playng games is a waste of time...
I mean....
Living is a waste of time...
A wasted time is a good wasted time!
Bye!

Yo dawg, I heard you like RNG. So we added more RNG to your RNG so you can RNG while you RNG. And if you rolled highier than a 95 a few times in a row on a digital D-100 then you get to go around and be a demi-god. Yeah, checks out for me.

Anyone who is against RNG gear to win based combat should stay far away from games like these. Leave them for the rest of us masochists to enjoy! Go back and play your LoL, DoTA2, GW2, ESO, FFXIV, Apex Legends, and such.

They really are garbage. Boss fights have never been fun în this game. As for the rewards, they are pure rng so as per usual bdo.
