Machinist is still the most fun, unforgiveable and fast paced Range DPS class.
The Machinist lacks of some kind of selfheal, but other than that, it can do nearly anything.

High Burst DPS - check
Support Members - check
Playstyle which needs your attention - check
Casting but still high mobile - check

I never regret to play as a Machinist. Some might say Bard is better, but in my opinion, Machinist is a lot more fun to play.
