Choosing a class

Well as the title says i want to choose a class, Rn i have lvl 33 Templar but its hard to lvl up with low Dmg and all by myself (other templars can relate) so i was thinking to reroll into another class is worth? or should i keep up on the templar?

Also i want to try a new class i always play as a templar or ranger never tried the other 6 classes

Pesonally I'd level a character to 10, do a LFG search during primetime, check how many classes are of each, chose a class based on those numbers. Clerics are the foundation of most groups so you should see 1:2 vs other classes.
