Don't need an FC to raid.

The current tier at least is completely doable through party finder.
Though since you're a little late to the party this tier, you might have a tough time clearing it before next cycle as there will be limited learning parties (but you can always make your own).

When it comes to roulettes etc, don't let DPS queue times deter you.
I sit in queue for about 20 mins tops as a DPS main for my daily roulette on my data center..
