Too many trolls lately.
Arena Sets are S1, S2, and S3, with the latter two being bought with arena points. With the introduction of 2.4, gold bought PvP sets will be available, and a few weeks after S4 will come out, so both S1 and S2 will be able to be bought with honour (currently only S1 is).
The Vindicator's set also costs only honour, and is comparable to S3.
Flaming is not a nice way to get information, and as Æethian has +5k more posts than you, he is clearly a more informative member of the forums, who is well respected, people aren't going to look kindly upon you.
