I am not saying warlight is always in a rock paper scissors situation, and i am not saying in warlight each of the "rock" "paper" "scissors" are equal, generally in warlight they have different "weight". But still, at many of the situations you need to correctly predict your opponent in order to make the "best" move.
Warlight, like any simultaneous-move game, is almost always in a "rock" "paper" "scissors" mode, thus the GTO strategy is almost always a mixed strategy. The GTO solution is almost always 80% move A + 15% move B + 5% move C. The percentages come from calculating the payoff matrix for each pair of move/response and solving minimax. This procedure automatically parses away dominated strategies, and assigns the percentages to non-dominated strategies.
On occasion, when completely lost as to what to do, I would select 6-7 options that I had, 6-7 options that my opponent had, estimate payoffs for each combo of actions, apply minimax to that matrix, and make my options much more clear. You could call that my form of meditation :)
