Let's post this here and hope ppl that wanno know, read it.
Little out of topic:
Retiring 15 times is max for the xp bonus. Other than the item nothing more is gained to retire 16 times.
That means that going from lvl 1 to 31 with maxed retire bonus and "average" multiplier of x2 requires 3066 tick.
(the "average" is more of a gut feeling sometimes you get x5 sometimes you get stuck to losing side.. maybe more accurate would be 2.5 .. oh well)
Time wise thats 51 hours of game play. (actually its even more cos rounds dont end on even tick's)
Lets put it this way.
If you wanno retire in one month, you need to play every day about 2 hours.
So if you start now..
In september you will be playing with your new wm weapon, that has exciting, +3 points damage and +1 speed!
And in december you can have 2 wm items!
Of course this required that you had maxed xp bonus. If not .. add 45% more ticks/time.
So how much you really value those 3 points of damage? Does it really help you that much?
Happy grinding
