Problems:
1) immediate teleport to busiest part of every map (entrances)
2) no latency between command to enter city and action
3) inadequate damage: 5 (mutants) x 2 (shots until they die) x 75 (average dmg per one rocket) = cca 750 dmg (+ knockdowns, cripling) on very long range (i.e., in Redding, if enemy is caping right bottom corner, under the sherrif, the place from south to downtown is death zone, because you cannot hide anywhere and they can kill you immediately.. not fiction, it is fact).
4) mutants are cheap and every era there was some bug so huge gangs could buy them without any limitation
5) you can use them from second computer and dont need focus to that char
6) zero prevention agaisnt supermutant leaders waiting over map
7) almost zero defence agaisnt mutants immediately spawned at city entrances, becauce you cannot aim their leader in the group (he is surrounded by mutants and there is not free pixel you can hit)
bad defence because even Scope is best you can use, FOCD granted real time switching aiming zones and PvP players in 90 percent resign to clicking to other zone, because if enemy are using FOCD kind of aiming, you dont have time to do nonsense mouse moves across your monitor
If any solution will not solve all those problems, it wont help. Even one supermutant teleported into grup of enemy does serious damage and evades focus, .. and you can always use them four or five from second computers...
