I do like what you started here! <3
So theres 3 daily story/bounty missions that rotate daily. These give you reputation, and this is how you unlock the boards and nodes.
(maybe reputation is aquired by guild to unlock nodes and ally points used to do the individual nodes on the board once unlocked by guild)
(Make these story/bountys accessable at say lv 50 so players can start gathering reputation)
So the board is setup like gw/ls/ds with different nodes increasing the payout as levels progress of the following... (brainstorming)
Board 1
1.)Credits
2.)Ship credits
3.)Guild shop tokens
4.)Ship shop tokens
5.)Arena tokens
6.)Galactic war tokens
Board 2
7.)Shard shop tokens
8.)Unobtainiums (maybe a low drop rate for a few pieces)
9.)Ship hardware (you know its coming)
10.)Gems! (A small amount)
11.)Ally points
12.)? Tba
Okay heres the kicker!
You have 3 chances daily, pending reputation/ap available (PERIOD) which node you clear is your choice, 3 different ones or same one. No refresh beyond 3. No retries. You lose, that is still one of your 3 tries gone. So access is limited by what you have in your roster, and NOBODY can do any node more than 3 times a day and those get harder for each daily repeat!
Now keep in mind this board is gonna be insanely difficult...even more so if you try to repeat a node. This board is designed with level caped players that have several teams g10+ in mind. (But a toned down, less rewarding beginer board should be available if reputation accumlation is guild orientated)
This also perfect way to make use of your allys as 6th squad member or as a forced ally in repeats.
(Heck some repeats of same node might include addition prerequisites like "must use CUP" or "ugnaught must survive"...you get idea)
Now again these rewards are pure, just the aforementioned categories...and you must clear one each node (once) to gain access to next one. (Or not) This can be incorporated into the guilds by making reputation something accumulated by the guild to unlock the reward nodes, or boards and then individual players use ally points to do the individual nodes.
*shoot, the nodes unlocked by guild via reputation can be reset weekly, monthly etc, or different periods of time pending guild size*
Each board (maybe intro a intro board with just say 3 nodes so players under lv 85 can get a feel for the end game big boy board that you unlock at lv 85) is same as previous but gives a increased amount of payout/access to types of node rewards.
You could even introduce limited time event boards as well...where you can unlock unique characters! This will give f2p/p2p both a chance at new things. And these limited time event boards would feature refreshs, but limited amounts of them, giving p2p an edge. But slightly.
Just an expansion of OP'S idea! I love it! <3
