PoE Gladiator, Multiple Totems, Fire builds

I haven't played since Ubers were a thing. I tried a Uber Eater on this build at level 93 with some different gear and got slapped. 6 portals gone immediately. Is this current version Uber/Sim wave 30 capable? Ive got 4.9k health, 47k armour with flasks, 79 all res/75 chaos res/ 50/42 block spell block and ailment immune.

Im tinkering with my PoB and noticing some inconsistencies. I have attack speed on 3 flasks but PoB only show one flask with attack speed in attack speed calculation. Can I only have one flask with attack speed? I also have 2% increased attack and cast speed with physical skills nodes on my clusters. PoB is not increasing my shield crush attack speed from these nodes. Shield has the physical tag. Am i misunderstanding something? PoB in question :

Hi All, Inspired by Phreak's spreadsheet breakdown today, I decided to look into a Shield Crush Glad. I looked at POB Ninja's first week of gladiator builds and put a few ideas together and optimized the tree a bit to get the following result: I'll probably be league starting this until I know what the best build is for Sanctum farming. This is a fairly standard Crit Glad build that should crush maps and have enough dps to get through t16s and the first set of bosses comfortably. Why Glad over Slayer? Glad has QOL(10% less damag

Firstly, the PoB - About the PoB - When initially brought up, the PoB will show a basic level 90 tree and have some fairly budgeted gear to emulate an early-mid range red map setup. The only truly expensive piece will be a Ryslatha's Coil, everything else is generic rare gear with a few needed stats as well as a mid range Crown of the Inward Eye, which might cost a bit in the first few days but will quickly fall in price as the league goes into next week. Also, the damage shown does not include both Warchief and Protector totems

Uniques are shown with mid-roll modifiers unless the uniques are very cheap (max attributes Carnage Heart). LEVELLING: Levelling trees are general recommendations. If you feel squishy or feel like your damage sucks, pick up damage/life nodes as needed. Make sure to keep upgrading your weapon with t
