I have 2 ancient watchers, 2 sunfury protectors, 2 hellfires, 2 shadowflames and 2 defender of argus in my deck. Shadowflaming a watcher usually wipes the board completely. They don't have anything with more hp than 4. So I feel very safe from early aggro. The time when they win, is because their stars aligned which i think it is normal for an aggro deck to win from time to time against me.
The fact with ancient watcher, is that they will never attack it before it's activated. It's way too inefficient to spend so much resources on removing a minion that cannot attack and has such good stats.
How many of you has only 1-2 AoE in their deck? Zoo doesn't have something like coldlight seer on turn 3 that suddenly puts the murlocs out of AoE range.
