It's an unintended side effect of what is generally a good system (use different icons depending on whether it's a "bot" or a "tank"). Cybran has bots instead of tanks for t1 because they look cool, not because of the intel game. We have to decide between two imperfect options:
-Mantis has "tank" icon even though mantis are bots
-Mantis has "bot" icon so it's harder to tell them apart from LABs
So either you have to tell people "diamond is a tank and hexagon is a bot EXCEPT for mantis" or you have to tell people "LABs look like this, t1 tanks look like this, but watch out, you can't tell Mantis apart from LABs"
It seems obvious to me which one we should prefer
