Would you rather spend all your time whining about the FOTM, hopping around playing whatever is FOTM and defending it, or just playing what you like and learning to hard counter all the bandwagoners? This is a serious question, because it seems like 95% around here will choose options 1 or 2 without even giving 3 consideration.
Think about the impact on yourself.
- Being angry about something you can't change directly is just going to make you frustrated. Sure, you can go vent/whine on the forums but you're still sitting around mad all night when you're supposed to be enjoying yourself.
- Rerolling the FOTM is a common choice. If you can't beat them, join them. But then you get bored because you're the same as everybody else or even worse, your constant bandwagonning leaves you battling the learning curve and people who have chosen option 3 walk all over you because they're masters of their class.
- Theorycraft with others, test abilities, test builds and discover what the FOTM is weak against, then capitalize on it using the class that you enjoy and are most familiar with. Not only are you winning a lot more, but you're proud of yourself for beating the big bad overpowered people.
