I had for a moment @37 24/24 shielder idea (8PS 8 ATH 5WM 5SH) but it's a bit risky, so still not decided cuz 21/24 is safe mode and still decent build.
The biggest snag is that there is no ideal solutions, and in addition devs can change formula and then again will be streams of tears, so you should rethink balanced builds.
My current build (@36) is almost perfect for me (21/21 7PS 7IF 7ATH 7SH and 7WM 170 1h) but I am tempted by this @37 24/24 and don't know what to do... but if it's true that we will get a free respec without penalty once every 7 days (subject to change :O) everyone will be able to try different options and it's fantastic!
