I dont know if anyone read the blue posts for the T2 sets but once you buy the first set for 60 tokens they get discounted to 40 once you buy one at 40 they get reduced again to 20 each so that plus 2 months for the event everyone should be able to farm them all.
If I remember hearing right, some items that are gurentee to return/are future-proofed are items like the T2 sets, and the timewalking items added to specifically to I believe WOTLK and, of course, Classic Timewalking which they have confirmed will be entering the standard Timewalking rotation schedule even after the event. So, yes, I agree, take your time, get what you really want and just have fun. For me, I aim to get the T2 sets, the Worldbreaker/Core Hound mount, and the pets since, well, when is the next time that baby bear minion will become available outside of the Black Market for millions of gold? (Though, funnily enough I saw Lil Wrathion on the market for a 20K gold bid which I think no one ended up buying.)
Don’t worry. No need to do the event. They clearly dont care about exclusivity. They just are giving away the 10 year anniversary mount in this event. All the rewards will be available again later.
You mean the mount you got for running the lfr version of an old raid once? Lemme tell ya waiting in that queue took a lot of skill and dedication. You even had to be max level and have some heroic dungeon gear, not to mention an active sub!1! SoOo eXcluSiVe...
