You’re cool with something that you can’t possibly block no matter what, but you’re not cool with something that you have a 33% chance of completely breaking? That’s not even coherent. You’re making it sound like TACs are a noob, easy-mode strategy that people can’t possibly deal with and just break the game. That’s not the case by a mile. Use it sparingly and it’s a risky option with a good reward, get obvious with it and you’ll be watching your combos get broken left and right, and that’s the case with a number of the strategies and tactics in this game. I don’t get what you’re so mad about.
And people who use it sparingly are ok, but people who abuse it put a bad taste in your mouth? How? If anything you should be thrilled that they do, it’s a free win for you. If they do use it and abuse it, chances are they’re not thinking very hard about which direction to send you and I’m willing to bet it’s always the same one and BETTER yet, they’ll always TAC twice per air raid, tagging in every character available. Punish them for it, it’s not even hard, believe me.
I’m not trying to talk down on you here, just pointing out that mindlessly TACing is a really bad idea and definitely not one you should be getting upset about.
