So I think mobility is seen as an after thought due to how people spec into resilience and recovery, since they tend to be more important. A way to make people not ignore it would be so having below 40 mobility will make one move slower than currently, this way the 3 stats have relevance behind them. Do you prefer less flinch and more health? Or maybe a faster recovery to disengange and engage, or do you prefer to move more fluently and with speed? This, I believe, would also make each class have their identity further solidified, rather than Mobility continuing to be a non important stat.
