Normal and Hard modes....sounds like the old LOTRO, when raiding still happened there...Tier I and Tier II (and Tier II Challenge).....worked great, until the different tiers started drawing from the same loot table, which contributed to spelling the end of it all for that game's raiding...

As long as there are completely separate loot tables, this is a positive step and will get more people into raiding, which is good for the elite raiders, as well.
