You don't need to doubt yourself, because there really is a problem.Well there is the problem. Rumor like this happen because BHG can not provide Proof of what was used in war battles. Yes replays are broken and so are War Battle reports there no one can prove Rumors false or true.
Now as far premium tactics truthfully I have hundreds of them, so my honest feeling is Troop Tactics are not being abused by most if at all. Yet I must admit it possible and we cannot prove it one way or orher.
Now hopefully BHG is good to their word that this will be fixed sooner rather than later. Till Replays and War Battle Reports are 100% legit rumors, falsely accusing, and mistrust of BHG will continue.
I know people who use this, and I used to use it too, though I can't provide you with detailed information about its source. I'm an administrator for a large Chinese-language community group, and I know players from top-ranking guilds, and I've personally witnessed screens showing unlimited items being used.
I just want to express to you that my position is real. Nobody would wastefully use items like this, especially against opponents who are already weaker than you, or in situations where you're already certain to win the battle. Yet you can still see many guilds using high-tier flags to attack, because those don't cost them anything, so they're willing to use them.
