It's not a disagreement. You're just wrong.
Treants and Roar is really good, especially against melee cleaves/prestampede nerf hunters. But so is Treants and bash, being able to lock a healer down, as well as both your kill target and the 3rd teammate without getting off your kill target is invaluable. What's better all depends on your comp or theirs, it's not black and white.
And if 'mr neverglad' doesn't like being called out maybe you shouldn't chat shit about stuff you don't know about.
Do not insult those you do not agree with. Infracted.
