I will only be playing matched play, unless I play with kids or newbies, then the power points seems like a good way to introduce new people to the game.
Those odd points I see complains about is a good sign that, GW for once, actually applied some kind of calculations to it.
If you like even numbers, just take units of even numbers like 5 or 10 models and you will have no trouble getting a 2K point army on the nose.
Why is calculations good you may wonder, well math is a science that is exact, there is no wiggleroom, which makes it a perfect tool for balance.
In addition, it will help when rectifying balance flaws. For example GW realized transports got overcosted, well just reduce the points they used for determine how much each seat in the buss cost.
Also if or when someone cracks that algorithm (or GW reveals it), we can start creating our own units, like in one the old tyranid codex´.
Edit:
I just watched a readalong on youtube, the 280 page rulebook is just filled to the brim with fluff, and then som narrative advanced mission rules. Biggest thing though:
Games of 1K-2K points should use the 6x4 table size, armies below 1K use 4x4 and armies above 2K use 8x4 or bigger. So Great, finally we have an estimate.
Normal(1K-2K) games also has a maximum of three detachments.
This is good news
