Recently discovered RoR, and i really enjoy it so far

However, as i see that t2 goes from 12 to 26, i'm a bit desperate on how to level up right now, since in few exp bar i won't be able to do t1 orvr anymore, and when i get into t2 i immediately get dumpstered, since the gap between 12 and 26 is freaking big..
Any tips ?
Any idea on how to level up my toon a little bit quicker ? are sc's the only way ?
Thank you in advance
