There isnt a single good xcuse or justification for solo queue..any what so ever that makes sense.
one thing is solo queuing because ur bored and cba to group at that point...or u need a fast daily...or you are burning time for something.
now..WANTING to solo queu?! in an online mmo?!where interaction is necessary?
like i said...stop being socially awkward wierdos...not being able to be socialy active outside your house is one thing..but online??!?!?you need help
premades getting in one estimate time- 10-15 mins
pmaking your own premade depending on the gear/skill cap you require- 5-20 mins
so ye..no xcuse to not be in one,..
...or maybe there are 1 or 2 ppl out that that have families/jobs/ etc that dont have a set schedule or hours a night to play...just maybe (I know it's hard for young/single/unemployed etc ppl to understand...... but usually I get on have 30 mins to play and solo que. That's everyday 30 mins here , 30 mins there, get the daily done and back to RL.
