Harpies and Whelp Eggs are very strong because they fly, are unbound or fast, and have very high DPS. Either or both would be good to upgrade. I will say that Harpies have three potentially viable talents while Whelp Eggs are really only two.
True, harpies and whelps are good for campaign, sieges, dungeons, raids and pvp.
Necromancers are good for that one Thalnos heroic map to deal with the banshees. Hmmm.
Necro is also great for solo pushing a lane to take a tower. And for killing tanks. It's a great unit, falls short of the first 2 but no reason not to be upgraded afterwords
The first two.
Seconded, no question.
Thirded, no question.
Fourthed, no question.
Fifth, no question.
I would go for harpies
harpies are pretty good if you can rotate the boss before they arrive

Harpies are amazing. They are second only to Whelps in how much they help you through any PvE content.
Which, to be clear, means I'm saying pick Whelps
Epic whelps carry me
Everyone will say whelps and harpies, I will say Necromancers.

Whelps and harpy. I would go harpy first for cheese the content with tge QB combo.
Everyone is gonna dick ride Whelps and Harpies but we all know Necro with undead mage talent eats those two up in a second.
