So the only tactic I've encountered so far, where I a problem with is Wraithguard spam. Please wait with your "Use meele"-advices before I explained the problem.
If the enemy uses them defensevly and has reached a critical mass round bout 5+ of them, you can't attack him anymore in his base. I recently had this situation twice in 1v1. The enemyl started spamming Wraithguards. He had 5 or 6 of them. The problem was, he stayed in his base. I was not able to attack the tower, with the Wraithguards because everything got shred what I threw at him. I even tried to snipe the Tower with Illum Zars, with little success because the Wraithguard shoot them to pieces (maybe I positioned them badly). I tried Banshees and they got shot before they could reach them, and even if they do too little damage. I even tried Wraitblades, but they were too slow even with a Warppotal. So no luck either.
The 2nd time, I was doing the same tactic. I got dominated and started to build Wraithguards, because I saw the enemy doing the same. He attacked my tower. I had 5 of them + hero and some Avengers. I killed all of his heroes including the Wraithknight and Jain Zar his Wraithguards, Falcon Tanks and a a few more line infantry. Needles to say that I won the game with the following counter attack.
Now we get to the Shadow Spectres. Wraith-units have Heavy Armor. Shadow Spectres should be the hard counter to them, but they cant. Out of the following reasons:
- Too little damage (for Wraith-Units)
- Lasting Laser
