Return of Reckoning

Hey,

So i leveled my Choppa to around 27 / rr19, with scenarios rvr / pvp and some quests.

However i read and see that t3 rvr is kind of dead and some dudes said if i just level i will be cannon fodder in t4...
So what should i do now? Grind through quests to 32?

Im bit of confused what i should ...
