Hi Vanguard, slightly off topic but hoping you could give me some advice. I'm 5 months into the game and was concentrating on one unit at a time.
I now have a Liberty Medium and a Liberty Howitzer at over 5m, all components / cogs full.
The howitzer is Lvl 89 ground part mechanic / wrenches and the Medium at Lvl 62 wrenches.
Question: Would you place all wrenches into one unit or balance the wrenches out, as you get higher level, it takes many wrenches to go up one level?
If balancing the wrenches out, what would think was an acceptable level for wrenches?
Last question, after the two units mentioned above, what would you concentrate on next SH, another Howitzer (Lib or Soviet) or ATG?
Thanks in advance

If they dont fix the bases i think a lot might start quitting
