It's sometimes difficult to escape our own situation to examine how the release cadence impacts the game for all playing levels. Part of the reason these high powered toons that have been released land on a single hard node is because 1) more established players should be able to refresh that node without consequential impact on crystals and 2) it prevents early-stage players from farming a late-stage toon out of "easy" stores.
The stores are established as early game farm locations. To maintain balance for early and mid-game players, late stage toons are relegated to hard nodes and high-energy cantina. Hence why the vets were put there. They are no-bueno, but JTR is top tier.
There haven't been any releases of synergistic teams since Phoenix. Vandor toons came out, but haven't landed on a farm location yet. Until that happens, we should reserve criticism.
A lot of the frustration comes from trying to farm all the new toons all at once. Pick the one that fits your plan. Refresh the node once a day (except when it conflicts with daily challenge) and you'd be surprised how quickly you get that 1 character to 7*. In my experience, the narrower my focus, the more enjoyable the game.
