They also could have been figuring in que time, as MSQ is a roulette very likely to put even a tank/healer into a que rather then go right away(or close to it). If we use your times(my experience says longer but is out of date and i choose not to update it), thats still an average run of roughly 42.5 mins(and since you dont know which youll get you need to plan on having the 50+ available anyway or you arent getting the roulette reward). In 42 mins with a healer que you could do leveling and 50/60, possibly with enough time left over to add in guildhest or trials(smaller exp and currency rewards for smaller investment of time). Most groups will finish alliance in less then 40 mins(and those runs are often more fun - although the que potential is also higher for this one). But ultimately, this info isnt to benefit me its for the OP and anyone else who might read this with similar questions. Im biased against MSQ and have no problem admitting it. If i were leveling something it would be the 6th or 7th roulette id get to(alliance, leveling, trials, pvp, and 50/60 would all come before it for me for sure though not necessarily in that order). But i did mention it because it has a nice poetic payout(useful if youre still buying gear), and from what im told its a nice exp bonus.

I forgot to mention the pvp roulette though(which i actually used regularly when going 60-70), so that was bad on me. Matches are fairly short(usually less then 10 mins), you cant talk to the other alliances so no trash talking the fallen(or being verbally abused by the other team while down), and the game doesnt force any type of class balance on the party(anything goes). You automatically get the whole PvP moveset for your class, and everyone is set at the same level and gear level so theres no advantage to be had/lost there. Its not too bad a setup. The more experienced players will typically be obvious, but anyone can figure out how to throw attacks at the other teams and do some damage. Rewards are exp, pvp exp(you earn titles), tomes, and seals(several nice glamour sets available) - and if you do the Garo event a couple mounts are up for grabs too. Everyone gets some, but there are bonuses for winning so you still wanna try.
