Towers arent doing enough damage to heroes, and dont change priority.

[Discho Tweeder]

Towers don't seem to be doing damage to players, or simply not enough damage. 30 seconds into game heroes can tower dive for kills. The towers don't change priority from creeps to heroes when they damage another player under tower. In my past history with MOBA's tower diving early in the game generally equals death.

I think they want it to be a faster game than DotA for example but yeah the Guardians seem especially weak. Although I do love the non-hero aggro that allows for more aggressive plays
