Well this feature depends on many variables but sure not on rushes...
Strategic skill depends on how fast you get resources, and on how you spend them, and the order of the upgrades, and the variety of buildings you build...
Tactical skill counts on tactical doings that you made during the match...
My friend once got 130 tactical skill without even attacking once in the whole game...
Tactical doings are like: Attacking units from behind especially pikemen with cavalry...
Using the bonuses that the units have in attack against other units...
For example if you attack trolls with lorien archers you will get a reduction in your tactical skill ratio, while if you attacked trolls using mirkwood archers you will get addition to the tactical ratio cause Mirkwood Archers have bonus against monsters...
The kill death ratio has a great role in tactical skill as well...
Also the order you destroy the enemies buildings has a role as well...
So these are the things that affect the tactical and strategic skills I guess...
Notice that new and weak players get a higher skill in tactical skill cause they make less mistakes because they do not do much events to make mistakes versus decent players who play a lot and lose points a lot as well...
But extremely good players must have a good tactical skill ratio as well as good strategic skill...
Thank you...
