A bit of agreeing, disagreeing and elaboration.

Crit teams don't have to be vulnerable now. With units like Maxwell who are quite bulky and units like Colt who are even bulkier crit teams are better. Units like Kira (dark, light) and Dion (coming soon, earth and thunder) specialize with specific elements. It is true that crit leaders like Maruideth and Vanberk are not as good, but 7* crit teams are decently bulky.

Oulu is VERY good once his 7* comes out. In spark/crit teams oulu can damage and mitigate at the same time as his attack is one hit and when sparked/critted can deal a lot of damage.

Exvehl (Ahvel) is very good as he has a decent 24 hit SBB plus status nullification and curing which is very important in raids.

Fahdahl is VERY good especially for the later stages of raid not because of status ailments because of his ATK and DEF down effects, the former the more important. As there isn't a ATK down nullification yet in the game, the effect procs on any boss, reducing their attack by 30% which may be essential when RC5 comes out.

tl:dr, DEF buffers are really important in raid along with mitigation and ATK down to easily clear raids. Raise Oulu, Exvehl, and Fahdahl. Crit teams are good since the entry of 7* crit leads
