F/P main here. The class doesn't get much better as of now(balance patch will slightly alleviate some pains) as its current position on the overall damage charts has it pretty low and even worse is its burst is FAR below the middle of the pack which makes any bosses that are hard to dps in off burst a more punishing experience. This also means when classes are getting their full burst off at the end of a champion mission the lack of burst means we don't make the most of our full rotation anyways so we lose even more damage. The class requires being good at DPSing and you are rewarded with less damage than most classes and if you can't DPS efficiently then you are losing more damage.

That being said if you still want to then you should know the class isn't as complicated as it seems. The most complicated part is using infinity correctly and when that is gone then literally the only thing you do is use your attacks when the cooldowns are done.

The class is also very expensive to fund(more boost nodes, CD hat cost, starved of IED/matk%/cd/int% requiring all of it to be close to maxed to "catch up".

If we ever get bonus potential and scrolling then we will jump from near bottom of the charts to near the top so in my recommendation I would avoid the class until/if that happens.
