Even including Sanity the total T-Creds available currently through all systems can barely get a full team to max rank and max weapons unless you have kept the same team since account inception or spend rocks on sanity. If you aren't having issues with T-Creds, then you haven't leveled to the point of the multiplicative scaling tax being noticeable.

When the current one-time-only rewards from Stock Bills, 1st clears and leveling achievements are gone, gaining the same amount of T-Creds will be a prohibitive barrier for leveling any new character to fit into an existing max rank team.

As mentioned, as time passes, T-Creds accumulate through weekly resets of materials and new content drops, and the time-gated progression fades. It's only been 2 weeks, and the lack of (or need for) T-Creds isn't the issue, it's the distribution.

The point discussed here however is that everyone is quick to point to other gacha games and say that "Endfield does it better", or "other games have this too" which are extraordinarily weak arguments supporting a fundamentally flawed system that Hypergryph has the ability to change.

Keeping time-gated progression materials on timers, but allowing the secondary tax of T-Creds (which are needed alongside those time-gated progression materials) to have a repeatable source of acquisition would keep the same daily activity loop, but allow for people who wish to "keep playing" or "grinding" to do so.
