Favor of the Sim, wanna use it?
Go ahead
Don't wanna?
Surely don't use it then, both are good

Now my biggest issue was that, at least on the time i did TEA, parties would take hours to even get close to fill so prog was both slow outside and inside the raid itself, so add to that reaching a far point like it is wormhole and having to reach said extent even further

So while sitting on PF waiting for said parties to fill sim worked as a double entretainment and practice for a future mech wich everyone would gladly welcome

Both using it and not using it are completely fine imo
