Just as a starter, considering that I've beaten Tinker in 1v1 I would consider myself as good/better.
At the start I wasn't as good but with the will to be better you will get better, no doubt about it.
The main thing I saw in your post Venomous was the 4 17 pounders and overwatch. This is the main thing, how is it realistic that comps will just get owned by your defenses all the time? Besides that, you end up relying on another team mate to go and attack afterwards. I can imagine a 1v1 you vs bots now..........10 hours later still defending!
I wouldn't say that humans are something you should be annoyed about. Everyone has their tactics, (and Dracula doesn't always do that) but its a better experience when you don't know what is going to happen next. Comp stomps are scripted, and in pvp's anything could happen.
The bottom line is, if you enjoy comp stomps, especially so that you can be lazy and camp defenses, then I fail to emphasize as it seems pointless.
