Lets talk reality/logic here.
You can get Merciless Gladiator/Supreme/Gladiator/Warbringer/Duelist/Rival/Challenger from Solo Q with RATING WAY less needed than what is needed to in 2s / 3s.
Yet again you can't buy neither shoulders nor 2.2k weapons from Solo queue.
You can get rival around 1750 rating 3v3. before even getting your 1.8k weps. ( you get a title which used to be worth of 2.2k back in retail with 1750 rating, in a server way less populated than retail servers. which means it should be harder. yet it is ten times if not more, far easier)
Which means the value of 264 / 270 PVP gear is actually WAY higher than prestige pvp titles right now.
you need the equivalent of 2.7k in 2v2 ( or even higher ) to GET something from Solo Q which requires 1950. NOT TO MENTION you actually get the lesser titles along the way ( MORE REWARDS )
I am not sure what is your business model is based of right now. but all this would lead to right now :
-Kill 2v2 Queue
-Less Shadowmourne Donations. ( who would play Hpala/Warr anymore ? yes the queue sucks and we all know it. but the problem is MAINLY with the meta. change it to 264 meta for 2v2 to be able to queue. Do not punish players for pushing rating above 2.5k ) so simply why i would bother with shadowmourne anymore ?
-More Wrathful Shoulders Donations ( the thing with 3v3 it was not attractive last season. forcing others queue to become obselete / less attractive WHILE Marketing Solo Queue AS AN ALTERNATIVE for rewards is meh. and simply wrong. i will donate those shoulders and get all my titles AND MORE like Supreme / Warbringer from Solo Q without playing a single legit arena match on this server.)
-Less 3v3 Queue ( Do i need to explain why ? i wrote it down above and you could figure out the rest)
-Titles will hold absolutely no value, Since every guy on this server got them right now. in fact gear ( shoulders / 2.2k weps ) hold more value right now.
If you want me to furthermore address how you can fix this as part of constructive criticism. I am willing to.
But i am pretty sure you have individuals in your team capable of doing so. other than the guy who came up with this absolute tragedy mess.
