baffling design choices.
Theres effectively 3 different passive stat trees.
commander exp gained from matches. leads to one skill tree.
A separate exp/hour offline tally(research). which leads to ANOTHER skill tree. both effectively do the same thing. passive stats, unlock squad/defender slots, and backpack/storage.
There is little to no reason for those two to be separate trees.
Then, those two both feed into what is essentially a hidden third passive tree, in the form of squads. THIS tree, is effectively just slots in those previous trees, which you place the survivor cards in. survivors effectively being passive stats.
Matters are made worse here. With team leads, and survivors.
And then Defenders, which while LOOK very very similar to the squad survivors, are an entirely different mechanic.
Oh, and "survivors" used in squads, are also a totally different mechanic and thing to "survivor" which is a currency for expeditions...
So, defenders and survivors look the same, but are two entirely separate mechanics.
And survivors and survivors are named the same, but are two entirely separate mechanics.
Why do expeditions even exist? Expeditions and research. two offline app game mechanics in this thing...
