Not really. Yeah, it’s a high risk - high reward attack strategy. With good initial boards, the defending enemy is toast in just a few turns. With bad boards, that is where mastery on tile movement and manipulation comes in. Since the probability of gaining and matching favorable tiles is at 20%, those players using mono and able to overcome with initial bad boards more often than not are people who have a lot of smarts in them since they are able to see some tile moves that would eliminate the most unfavorable tiles in anticipation of them being replaced with favorable tiles, making diamond and dragon tiles. I have several instances where cascades have filled my mana twice over while killing or maiming enemy heroes. I am not saying those that do not use or advocate mono are not smart, I just think that mono users are a lot smarter as they have higher level of tile movement mastery, use their heroes’ skills to their advantage, optimize the total tile damage against the enemy hero, take full advantage of the Element Links, especially if you have more than 1 HOTMs with distinct E.L.s. I do agree that mono is not for everyone. It takes a lot of practice using and mastering it.
All i am saying is having 2 modes of killing the enemy heroes (tiles and skills) is far better than only relying on heroes’ skills alone.
