Tii, NOPE
all officer are waisted money. I had near all at level 10.
Vasja took all and gave me 50% of hc back.
And cost for rebuy grow so much that I have some level 6
some 0.
Only battle experiance points are important.
all other stuff is wasted money.
No secure invest.
buying all officer you need 5000 Euro.
that would be a lot high end games for playstation and such. :D
