The thought `It’s all just luck`
The reason most gamers give after each loss is to blame `dignity` like guy A and B are lucky so they have a 3-star general, if I’m unlucky then I’ll lose.
Even rolling a 3-star champion is not necessarily a matter of pure luck, some gamers have even found ways to increase the odds of getting the champion they need (details you can find out HERE).
Roll for `pleasure`
Rolling or refreshing the store is an action that everyone who plays Teamfight Tactics does, from Guild to Challenger.
2 coins may sound small, but if you roll without calculating, your money will drop dramatically.
Only play a single squad
It is true that in each season of Truth Arena, there will emerge a few teams that are extremely strong and superior to the rest.
The meta is always changing, currently every day there will be a new team created by gamers to make the game not boring, another thing is to avoid overlap with current strong teams.
Refusing to observe opponents
Although each player has his own arena, the secret to winning in the Truth Arena is to observe opponents and come up with countermeasures.
Observing the enemy has many advantages such as seeing how the opponent arranges their formation, what team they are playing, how much money they have left… Then you will find the best plan to deal with them.
