Iron Duke ,
blueberry , I will get back to EW5 eventually and as I see with these new princesses' updates it will probably be necessary to upgrade several low tier generals. And that is something I can do now without spending time for playing:)
Could You guys advise what are the generals that are important to upgrade almost for sure?

2 - Moctezuma, El Cid, Richard + 1 free slot
3 - Moctezuma, Petain, Edward, Lincoln, Nelson, James Wolfe
4 - Moctezuma, Pachachuti, Petain, Edward, Lincoln, Richard, James Wolfe
5 - Washington, Moctezuma, Pachacuti, Richard, Petain, Edward +1 free slot
6 - Washington, Moctezuma, Pachacuti, Richard, Nelson, Petain, Edward +1 free slot
The hardest missions are usually the last three, more or less, so just upgrade the required generals for those. Maybe you can go cheap on some of the weakest, like Conrad, James Wolfe and Henry, they weren't really useful.
From easiest to hardest I'd rank the trials like this: Teotihuacan, Kazan, Patras, Isle of Man.
