What track record are you referring to? Indis and Geos don't stack together. AFAIK, they never have, but I tested it back maybe 2-3 months after SoA launched, and just retested with MAB, Regen, Refresh, Malaise, and +stat, and just as before, none stacked.
For sure, on Fury and Frailty it ends up being over a 6% further buff/reduction, Refresh is straight +5, Regen is +10, stats are something weird, I don't remember and haven't checked what their value was pre +5. I've long since forgotten how the tiers progressed, and neither of the Wikis ever had the information, just the caps. Assumed it was +5 tiers, but idk about that either. Regardless, don't you jinx my hopes of another capped haste option! ;O
Good thing it only needs to be 28% then with bell/Ergon, to be able to cap magic haste with bubble + haste spell, just like Brd caps with relic 2x Marches + haste spell, assuming Geo-Haste is magical haste.
