I'd argue that playing the luck class without crits is pretty antithetical to the class but honestly crits are pretty crucial on... almost all classes save a few that benefit from not critting. As an ecaflip you have a few pretty good ways to find crit chance in your kit. Clubs, Fleas, Lucky day and the precision passive that gives you wp back all give you extra crit. 
Choosing to opt out of crit forces you to play a resource management game when you enter a fight do you reroll that card or choose...

for better or worse a lot of MMO games are starting to drift towards the single player mentality.

If you're running a single target build you should be stating single target mastery. Those secondary masteries give 8 mastery per point and the elemental only gives 5. Your damage will suffer in the long term if you choose to just go for elemental mastery.
