And this is exactly where the AI fits in. It is part of the plan and requires strategic thinking. It mean people have to deal with AI units and not only focus on other players. It means to deploy counter-measures. If a team cannot stop a couple AI units it is incompetent and deserves to lose. It is easy to distract AI units and stop them.
If anything the AI units need to be made more effective at taking over bases simply to counter spawn camping and other awful things where no one cares about the actual objective.
I've been in plenty of games where a single doom shroom or an ice shroom ended the game. Because no one in the zombie team cared to take those out, so the few zombies with the intention to take the garden were in for a surprise. You would think after 3 or 4 people got rekt by those potted plants, someone would take care of those. But no. And that is when one team deserves to lose.
With all my experience i can tell you that AI units mostly fail and are free points. What you fear is only a very rare problem and sometimes even a solid strategy to crack the defenses. If you cannot stop AI units because you are under constant fire, its your teams fault for not providing you with cover. If its 12 versus you its your teams fault again. The AI units have very little impact on the flow of the match.
