Definitely, I loved how Illidan was freed after all that time and the first thing he does is take out the strongest dreadlord in the entire Legion lol.
I'm pretty sure the devs of WC3 mentioned there was going to be a mission planned to be exactly like the one you mentioned, clearing up all the remnant forces after Twilight of the Gods, but they realized that after a brutal 45 minute defense you probably wouldn't want to sit through another mission.
Brothers Stormrage was so hard for me that I just opted to rush Red's base in the middle with dragon turtle spam. Fighting AI undead makes you realize how obnoxious they are, every unit you own will have Curse, Cripple and Disease Cloud in like the first 5 seconds of fighting.
Gates of the Abyss is a really cool mission lorewise, loved the tie in to WC2 and how Magtheridon had repurposed the portals. It's really brutal early on especially when they bring in the red dragons since fel orcs + Unholy Frenzy shred buildings.
Playing Lord of Outland makes me sad because you realized it's the end of the Blood Elf campaign, but it's an amazing send off mission. His triumph in Outland makes his defeat in Northrend all the more crushing though.
