We all know it needs fixing, and after reading probably too many posts on the subject I've got some ideas on how to fix it. FFG may I recommend the following 3 step plan:
1. Add the Sensor Slot. According to cannon the RZ-1 has a powerful sensor package, as it's designed to be a reconnaissance craft with hit/run tactics. If this change were to happen, I think that it should coincide with the release of an (RZ-1) A-wing specific sensor upgrade (see hotshots and aces v2.0), called "Short range jamming array". I imagine it would read something like "After you fully execute a blue maneuver, you may assign an enemy ship at range 1 one jam token." This would let the RZ-1 get even more up in the fray, while causing a little bit of havoc. Additionally, advanced sensor Arvel, would be a lot of fun to play, because you would have another method of getting a range 0 modded shot.
2. More Pilots. One of the biggest issues with the RZ-1 right now, is its lack of pilots. 3 more solid pilots that are I4 and above, would be huge. I think we need Tycho Celchu, Gemmer Sojan, and Shara Bey. I have also heard Hobbie recommended.
Tycho Celchu (I6): While you have two or fewer stress tokens, you may preform actions from your actions bar.
Gemmer Sojan (I4): While you attack or defend, if you are at range 0-1 of an enemy ship, you must roll one additional dice.
Shara Bey (I5): At the beginning of the engagement phase, you may spend one focus token to preform a red coordinate action.
Hobbie Klivian (I4): While you aquire or spend a target lock, you may clear one stress, strain, or deplete token from your ship.
3. RZ-1 Specific Talent + Access to Reload. I think that there should be some incentive to flying many of these together. Similar to the way that droids in CIS are encouraged to fly together. Something along the lines of: "While you preform an attack, if there is a friendly ship with this upgrade card equipped at range 1-2 you may spend one stress token to change one blank result to a focus result. After you preform an evade action you may preform a red reload action." The reasoning behind the reload action is that the RZ-1 was outfitted with 12 concussion missiles, and were often used as missile delivery platforms, so giving them access to the reload action seems thematic.
As always, I am sure that there are many flaws with my ideas here. Please point them out and let me know what's wrong! I love hearing all the good ideas!
