Ironically, my biggest issue with Legion is lack of optimization. Legion grids are very tedious to set up to begin with and when I play a character that has a different main stat as the one my Legion grid is set up for, it's really stressful to reorganize the grid to better suit my other character where it was easy with character cards (only switching out mainstat cards and less than a handful of others).
So my suggestion is to add Legion Grid Setup slots that allows players to create more than 1 legion grid that can be swapped out at will to fit whichever class they're playing.
The minimum anyone would need is at least 5 slots- 1 for each class type
I'd like to see a hot time event where Nodestone related things are enhanced.
For example: Raising chance of nodestone drops by 20%~50% of original rate.
Double Shards received from disassembling nodes
Node EXP Doubled (or high level node exp requirement halved (as in nodes level 10 in up)
Increased chance to only get nodes your class can use.
Allow nodes to combine with any same type nodes for a quarter as much exp as when enhancing with the same exact node. (Same type = enhancement + enhancement node/Skill Node + Skill Node. =/= Skill node + Enhancement/ vice versa)
