Is prioritizing Upheaval by level 7 as Warlock griefing? Can you leave heal as level 1 or not level it at all till level 10?
I had an opponent last night where he went straight boots and tangos starting items. He got level 1 Upheaval and just do Upheaval things to harass us in the offlane as it is so difficult to stun him when he hides in the trees. Is this considered a bad practice as it shoves the wave or can you just Upheaval the enemy heroes so that they coudn't reach for last hits?
