ravager do beat levelers 1v1.. but..
levelrs have:
aoe: this multiplies the power of levelers sometimes as much or more then 4 fold
solution: = spread units.. not easy for the next reason
concentration fire: concentration fire is a very strong mechanic.. eg. 10v10.. one side is random the other concentrates all units on killing each unit in series.. because it takes 10 shots to kill each unit after just the first shot the side thats firing random has already lost 1 unit and there damage output is reduced by 1/10.
solution: also employ concentration fire.. not wise if you have short range and the enemy has aoe as your units may clump
high alpha burst: slow reload but fast high damage projectile can diminish enemy numbers before the combat losses can average out..
ie. 4v4.. levelers fire instantly now its 2v4 and the true battle begins
solution: send scouts in a steady stream ahead of the attacking force to draw the inital burst.. difficult to time this correctly
defenders advantage: can shoot before normal in anticipation of intercepting the incoming unit with the projectile
solution: cloaking
true solution: imho levelers are glass cannons.. you must harass them with long ranged units to bait them into a doomed assault vs your ravagers as the ravagers in a spread formation wont suffer aoe or defenders advantage.. if your spamming scouts you can waste there alpha and it should still be a win even without concentration fire. to this end i advise badgers to force the enemy to become enraged
