Thanks all, thought I am the only one having this?
Hope Devs are reading this...
This seems like a major flaw on the original game, really before we debate on what "fantastic features" should be added etc,
the basic game have to be playable or otherwise..."broken"?
I would suggest a cap on max team number (9 as max) to avoid this or if possible enlarge the tactical map (with 18 as max) for long term bigger battles consideration.
(having 14 people team was a big fun anyway - epic feeling like commanding small army not just same, repeating battles which being nerfed because the of the focus of strategic layer - we can always click automate battle to focus on strategic layer right?)
