TBC=WoTlK >>>>>>>>>Legion (so far)>Cata (don't tell me about DS, everything else was ok)= MoP >>WoD
facts: WoD is the only expansion that got me so uninterested that i played...6 months...and not full time, mostly because i didn't have something else to do...
In MoP i had a good time because of most of my RL friends playing (40ppl) so we've done things, from arena/rated BGs to HC SoO (pre-nerf). The whole game was meh... but because of company it's my second best era.
Cata was ok, then i got in the army (literally missing 1year of DS.And again i wouldn't care, as i know me, i'd invest to alts and i would be ok).
WotLK had a shitty start imho, but then we had the best PvP seasons in terms of balance s7/8. Also raided everything up to 10man LK.Didn't killed LK, doesn't matter...i had a good time with friends and both guilds i played (the 1st one disolved due to transfers, the second one was more casual...still we got 2 10mans LK till LK).
TBC i had my best time, Full PvP... not as balanced as s7/8 but s3/4 send best to them. I was way in to the game... and high ratings and stuff. Didn't raid much, i started BT to Sunwell...didn't care too much about that also, but RL friends got me to raid. It was fun doing stuff with friends...!!! Only good memories from TBC...
Legion... all good and stuff, i like the game very much... i like the thing that my main is main (i can't play alts that much, but i've got things to do with main so everything is ok... quality over quantity -?- ). One big problem that just destroys the whole experience for me ...RNG .
I can't stand RNG in gearing. I believe if i quit Legion relatively early (not closed season/waiting next raid break... quit like i did with WoD, never touch it until end) that will be bacause of RNG gearing.
And i don't mind Rng drops etc. they were always existed, but at lest you could fill some slots that you were unlucky with drops... now, i need 1 damn ring with my favourable stats and it never drops...like never never...but i have like 5 cloaks with similar stats in the same ilvl
So i already started login less and less...like do mandatory stuff (AP quests and 1 dung/1bg/1 2v2/3v3/rated bg and alt-f4, when i have raiding i raid and maybe 1 mdung per day).
You know, seeing everyone else droping 860 and 870 gear WITH their stats in HC dungs, while the best thing that gives you is Blood of Sargeras or in the luckiest moment extra AP - i don't whine when it is AP- ...yy starts feeling boring... way too much boring...
Also when i finaly get a drop it would be vers-mastery for shadowpriest..which means chaos crystal>enchanting>gold.
