So I've been thinking about the "mount creep" that's been going on and decided to discuss something that's been mentioned, but not really discussed in depth so far. Forget about mount creep being lore breaking and overwhelming for other factions to deal with; it's overwhelming for lords in the same faction, making them outclassed in areas where they should be top-dogs. Or in the High Elf case, top lion
Case in point is Bird Teclis (AKA Birdlis or Tird). Before he received his Arcane Phoenix mount, he filled a niche within the High Elf roster, and it was a solid niche. He was the most powerful caster in the roster with some devastating bound spells, but he was fast on his horse and fragile. However, he is not the fastest thing in the game and good effort needed to be put into protecting him. Teclis was already good, and with his spells and abilities he could even through down in melee, although it was for a limited amount of time. With his potions, he could recover HP back, giving him a bit more survivability. He was in a completely different vein from his brother Tyrion who was a scary and fast duelist and pretty beastly when fighting anybody in general. They both offered different things within the roster.
Come the Warden and the Paunch, Eltharion is released and boy does he bring something new. He's a hybrid melee/caster/support lord with a flying mount! Awesome, right? Yes, but hold onto your butts because there's a "new" kid on the block and he is better in literally every single way. Birdlis. He has by far the better casting, he's better in melee, and while he lacks some of Eltharion's support his winds of magic pool is so insane that he more than makes up for the difference with the ability to cast a stupid amount of spells. All of a sudden, Teclis is a tank and melee terror that Tyrion cannot match, and he even gives Imrik on a Star Dragon a run for their money. With his insane casting, he can heal almost as much as Alarielle but is far more tanky and better in melee. Teclis, the dedicated fragile caster, is suddenly better in melee than the dedicated melee legendary lords, and is so absurdly tanky that in most battles that I've seen with him, you have to flat out ignore him and remove the rest of the army so you have the burst damage to kill him. It completely breaks the internal balance of the HE legendary lords, makes a lot of the lords irrelevant, and turns Teclis into something that, in the lore, he never was, never was intended to be, nor even should be. Same goes for Alarielle with her eagle, to a lesser extent. It makes her passable in melee and with 110 speed fast enough to outrun almost everything in the game, if not everything, so she doesn't really need protection in the air. Pretty much just have to ignore her while she prints a new Star Dragon. At least she didn't branch too far out of her role as a fragile healer and start whipping on enemies with the same skill as Tyrion.
And that's just with the HE. Wulfrik is another great example. It's pretty clear that sitting up on a mammoth contradicts the fact that he's cursed by the Chaos gods to be an in-your-face duelist, so even if it was within his character to ride a mammoth I don't think it would be allowed. But having Wulfrik on a mammoth makes the Marauder Chieftain completely irrelevant, unless you want to cut some cost but the abilities on Wulfrik are almost always worth the extra money. I honestly can't remember the last time I saw the generic lord in a MP match.
Same goes for Lokhir, but this time it's reversed. What was a chance to make a scary and good footlord that would blend infantry and go toe-to-toe with anyone who tried to goon him suddenly is just a Malekith without spells. Nothing really special or that impressive. If you want a flying lord, just take Malekith. He's better in every way, and the extra cost is worth it.
Those are just a few examples, but it's the case with most lords with mounts they shouldn't have. They lose their uniqueness when they gain a mount they shouldn't have. They ruin the uniqueness of other legendary lords when they gain a mount. Tyrion and Eltharion are just worse versions of Tird at this point, and that should not be the case. Each character offers something different, but by giving everyone a mount everyone starts to offer the same thing. Please CA. Remove some mounts and stop adding mounts to lords who shouldn't have them and usually don't even need them.
