I want to start this off by saying, I very much enjoy Criterion dungeons. Even the Savage version. It is a brutal test of skill that is incredibly rewarding when you push yourself further. However I do believe the system has some flaws in it that I want to express somewhere before we move into Dawntrail. So please allow me to give my opinions on these dungeons, and bring some suggestions as to how I feel they could be improved.
Variant Dungeons
I'm going to be perfectly honest here, I didn't particularly engage well with Variant dungeons. The concept of them is somewhat interesting, however the result of exploration ending up to be as basic as a minor change in the next dungeon boss' mechanic does feel somewhat anti-climactic. I'm glad to see lore associated with each one, however doing effectively the same boss 3-4 times if I get all the steps correct is a little tedious to me, and if I get them wrong it's another time round figuring out what I need to do. I quickly went to follow guides to get the mount unlocked because of this, and for AloAlo I haven't even yet ventured into some paths because I found the Criterion bosses so different and fun, I didn't particularly have value in approaching Variant anymore.
I would love slightly more intricate puzzles and map design. Give us a room where you get a 3 x 3 grid of tunnels, and setting them in different ways allows you access to different rooms or maybe even different bosses. Introduce slides where you can move left to right letting you dodge obstacles and gain some kind of resource as you do. Give us adds that require us to do mechanics so we aren't just pressing 2 or 3 buttons over and over until they die. This world of dungeons opens up such a big realm of possibilities, and I really want to see them being utilised going forward. I did not feel like my time was spent well exploring Variants and I would love that to be proven wrong in the future.
Criterion Dungeons
This may be a little bit divisive to some, but honestly? No notes I love this content. Other than some minor quarrels with boss designs (as a melee player in Criterion WOW did someone hate melees on the design team? I just want uptime) this is probably my favourite content in the game currently. It is quite hard, it's so fun having this much player responsibility, it truly is fantastic content and I highly recommend people that you should give it a go for the sake of the content it is, rather than a need of reward. Rewards will not go amiss, and we'll get to something a little later that I think would benefit from having rewards from this; but please, get a group together and just ram your heads at these fights. There is some really fantastic design in here that I can tell is trying to teach people to improve in other Savage Raid fights.
