This is kinda the problem you had with Resbots and Juno- moving them down made them useful.
At t2 you tend to just want to end the game with brute force and economy, something spammy and powerful, less nuanced and micro-intensive.
Its also the reason you dont see a lot of use of things like Commandos, cloaking units, EMP units, Combat Engies (Used as mobile factories to actually make armies behind enemy lines etc, i mean). They get used, but less than they might.
That being said, we moved some radar units to t1 in CA. They're still rarely used. Ive considered combining them into a single 'information warfare' unit, as was mentioned here. The self-jam thing is no problem- once aunit is under the jammer its in LoS and any cloaked unit getting close will be spotted by the radar before its under the jammer anyway.
Of course, that would make it redundant with the radar on the Flea, which is, imho, a misfeature. Give the Flea all-terrain if you want to give it a special power - that's the power it had in OTA. Of course, at this point we're moving a lot of stuff around and ruining stability.
AT fleas can be fucking crazy. The CA flea is AT, people were spamming it along cliffs, it was brutal on Charlie in The Hills. Even with a line of LLTS facing every single cliff, it takes one flea to get through and there goes all your wind. We had to nerf it (yes, lol, nerf flea!).
In the end though being able to park it up cliffs, scouting/raiding inaccessible areas, etc... it makes the unit more interesting (But thats more a CA thing to do.
).
