Don't do what pepe did, always max ps, ath and wm for an infantry build. 4 ath and 24 agi is a massive waste
I agree on the first half, and I call bullshit on the second half, regarding the 24 agility.
Now that the levels got increased and you can use higher builds, I highly recommend 3 things.
1. Get 18 STR
2. Get at least 3 shield skill to protect yourself from the ranged benders
3. Max out your athletics and agility in overall, and I`m saying this because with higher agility and maxed out athletics you get very good speed bonus damage, and also having 7 or 8 athletics goes even better with medium/heavy armours, because you can be agile and have good protection at the same time.
The build I`m using at this moment is this.
18/24
6 ps
6 if
2 ss
8 ath
8 wm
(you can reduce your wm by 1, and add it to your ss)
