Starting with the biggest issues with Blitz I’ve found are as follows;
Quantity vs quality- Since we’ve adopted to this method we haven’t lost a single game, play as UNSC or Banished and only make units that are >60 cost for the most part.
Your 3 scorpions costing 330 pales in comparison to my army of little guys, especially when I have a few hunters, few anti infantry and whatever else I want in between, and the best thing about only using weaker units is you can spawn them in really fast, much faster than the enemy.
Leader powers - A single 160 power MAC will NOT kill a 190 cost Atriox chosen unit, it will barely even damage the unit, but a single 60 point wild jackrabbit with BLAST will kill two in one blast. That’s right, a 60 point card can kill 380 points worth of Atriox chosen cards in one blast, doing more damage than a 160 point MAC blast.
Super units can be used too often- Sometimes my team of 3 have won games solely because we keep spawning Condors and Scarabs at the end to maintain objective control, we will be cycling our hand constantly to get the Condor/Scarab back to use it again in 40 seconds.
Overall I personally feel the biggest imbalance in this game is the quality vs quantity. It’s extremely simple strategy and unbelievably effective. Grunt mob, chopper, engineers, elite scouts, hunters and locusts. An army of those guys will pretty much beat anything at any stage of the game, suicide grunts help in a pinch but the best thing about all of this is you can spawn the same army in seconds at home base and be back anywhere in the map in another >15 seconds. And I can’t think of an effective counter to this, it takes too long to make a bunch of scorpions or vultures and I already have 3-4 anti units for those units and the UNSC doesn’t have enough anti infantry to counter the weenie army I have and once again it would just take too bloody long.
I implore to try this strategy, it’s extremely effective and needs to be rebalanced somehow.
