No it made no difference at my level either (And I saw all my same oponents make ADA like last season), when both teams had similar stats either team could take a full barrage. The average hit was very low. The weapons strength is it's fire/energy boosting effect, and paired with the right heroes I hope it's a worthwhile weapon. I plan to test it today to see how much increase/decrase it grants.
It only made a difference when one team was outmatched, as I could wipe a much weaker team with ease when using it, but I wipe a weaker team with ease using any combination (as does everyone).
So basically, it made almost no difference at all. If you were losing to firestarter, you would have likely lost to whatever else the team would have been using.
The real problem was the added time in the battles. But even that wasn't as bad as people made out. What people failed to realize is that it effected everyone, so for someone to say they missed ADA because they lost out on an extra 10 battles, well they also got attacked by 10 fewer battles since other people were tied up as well.
Unfortunelately, PD does not seem to care about anything. Look at IOS and the Armoury hacks. If the Android ver gets that bad, then the only way to win will be to cheat.
