I love it.
T6 is a very popular set. But, if they continue that road and just update old Tier sets, im not sure ill give them the thumps up
But for T6, its cool
I think it's pretty cool that they're doing a wholesale re-creation of T6, primarily because those sets routinely find themselves near the top of any fan-favorite lists and secondarily because the content they originated from (Black Temple) is absolutely a fan-favorite in the grander scheme of the game; with that said, I don't think it'd jive well if they decided to do this often with just any of the older tiers that may seemingly have thematic overlaps... with two exceptions:
1) I expect fans would be largely alright with a re-creation of T10, for the exact same two reasons as stated above.
2) I expect fans would be largely alright with a re-creation of either T3 and/or the OG Grand Marshall sets, for the exact same two reasons as stated above.
