A few points on this, ol' pal.
1) JTAC slots we absolutely require Comms. (We have 2 slots on each 'side' with specific JTAC recon vehicles supplied in our current missions now.)
2) Depending on mission, the emphasis shifts. on our Op. Lermontov, there is huge emphasis on A2G with major A2G tasks-arcs being complimented by at least three sub tasks. You can either do it the hard way, or read the brief, use comms and do it the easy way, in other words. Other missions are more straight forward.
3) When we are satisfied with stability in future releases all the associated AI features, AWACS, EWR, Tankers etc will be reintroduced, as they were in previous FC2.0 revisions of the various missions.
