I don't think it'll double again, it'll just be another 130-135 on top (as that's how much it's gone up both times so far). So ~400 ish.

At this rate, it wouldn't be until end of 8.0/start of 9.0 (!) that we started getting into 4 digits and even if we did... does that matter? It's not related to our job level.

At 2 years per expansion, 9.0 would be around 2026, we have some time :P
