Be honest - when a popup appears with a YES/NO, 90% of people will click YES without any consideration or care for the 'why'.
As for me, really like the normal Alexander fight so I sign up every so often (once a week at least for the gear), got two squishy tanks (one off-tanking due to inexperience) and a co-healer with bare minimum IL to sign up in my group. Some DPS didn't even enter portals, so safe to assume a chunk of them weren't experienced either. Basically boiled down to the co-healer dying repeatedly, burning my MP regularly to raise them, a tank getting chunked to 20% per bust, me having to enter a portal, the off-tank dying to mechanics, me actually getting to LB for once to raise everyone (was just me and tank at one point) only for the main tank to die, me having perma-LB aggro until killed while the alive OT can't find his aggro buttons, and the whole thing being an amusingly messy wipe at 5% HP.
