Oh my god, this reminds me of so many MMORPGs.
Doing a calculation with the max of 252 points for a stat confuses me a lot.
However, you could just max out 2 stats and have 4 points left over, although that won't make for an effective build.
You could put 84 points into each stat as well. You would have 4 points left over.
You could put 83 points into each stat as well. You would have 10 points left over.
You could put 82 points to each stat as well. You would have 16 points left over.
ETC.....
So, you see there are sooo many combinations!!!
Side note: Each pokemon has specific stats which benefit more, right? In many MMORPGs, it wouldn't make sense to give mages STR and AGI, since they don't boost any abilities/help that much at all. People usually go hybrid INT/STA or something else along the lines of full INT/rest STA but never STR/AGI/etc.
So, you should also consider what type of pokemon you are upgrading and what stats its abilities depend upon.
You would never want to spend even one status point in a useless stat such as STR for a mage.
This becomes more complicated with PvM and PvP...since there are infinitely many builds and there will always be players who are stronger than you and those who are weaker...
******You would need to check out builds on forums for the best way to upgrade your pokemon although******
Many professional players know what builds work and don't work so it would be wise to read up on some of their insights.
