Some players are neurotic enough to care about the difference between 50 points per model and 60 points per model. Others are neurotic enough to care about the last 15 points in lists. It seems there are a fair few neuroses going around!
I you don't like minis that come in odd numbers, then don't bring any! I hope you aren't too uptight to avoid a few units in an army list, amirite?

When I looked at the newest rules, I just about gave up on playing the game. My collection of Epic 40k Guard didn't have any units in the right numbers. I had maybe 3000 points worth of minis, but not enough to make any of the core formations. Part of this I blame directly on the inflexibility of going for even numbers in points values. Particularly in a game that's out of print and often features minis from partial collections like mine, this inflexibility seems like a less-than-welcoming stance. I understand that 25s are pretty, <CS: removed> but I'd like to cast a vote for points by-the-model if you please, and granularity in prices will not only help with that, but help clear those last few pesky points at the end of a list.
I resent that I can't ever use 2 out of my 6 Whirlwinds, for some unfathomable reason. It seems odd that Ultramarines won't field them in any number but four. Four shall be the number thou shalt count, and the number of the counting shall be four. Five shall thou not count, nor thou count three, excepting that thou then proceed to four. Six is right out!
