User blog comment:YourPrivateNightmare/Sejuani, the story, the problem, and the possible solution/@comment-1330314-20141105073012

Not every jungler needs a heal or a shield. If you think Sejuani's early clear is too weak, then the best solution would be to buff her passive, base damage and/or base stats to put her up to par. Though you may dislike her passive, it's a healthy, simple way to be tough in the jungle and after initiating, which is what she's meant to be good at. Reworks to abilities only occur when they're unhealthy or when they don't fulfill the champion's gameplay fantasy, not when they're statistically weak, so her passive does not need a rework.

Beyond that, what you're proposing are buffs to parts of Sejuani that she absolutely does not need. A mini-Frozen Heart + shield does not help her clear in a way that her armor steroid can't already, and just adds a debuff she doesn't really need to be effective. If anything, it would be worse than her current passive: Frost Armor lets Sejuani dive to the frontline, and then power through the slows she might receive along the way to reach the back line, whereas the version you propose would just reduce the attack speed of the tank, in most situations. Again, a buff to her armor could improve her clear in the same way a shield would, and the armor she receives would work better with the upcoming sustain on Hunter's Machete.

A heal fits Sejuani's theme even less: Bristle is her vehicle, not her healer, and she has no need to sustain in combat because she is focused on initiating and not dueling. Again, her current Frost Armor helps her tank and maneuver better post-initiate, whereas the healing you propose doesn't really do much for her initiation, or even her ganking power.
