So, there are enough fire powers that slow, immobilize, attack Fort, etc, to be able to take powers like that at all levels without extensive multiclassing? I punched in "fire slowed" into the compendium and there are 21, including stuff from spellscar, paragon paths, and a number of them don't actually cause the slowed condition to an enemy (one is the magma genasi's racial power that causes you to be slowed, and a number are powers that give your allies bonuses to save against being slowed). Also, one of them is only there because fire is in the title, it doesn't have the keyword. Not to mention a number of powers that are both fire and ice.
It doesn't matter if not EVERY cold power causes slow/immobilization ... or that powers with different keywords do it too ... but when a keyword DOESN'T do it, or does it rarely enough to no matter, you end up making a choice ... specialize in a damage type or get an effect.
A pyromancer, for example, has two powers total that have slow + fire, and one of them is prismatic spray. None that immobilize. So yes, there are niches that, at the very least, certain damage types do not cover.
I would go so far as to say that every damage type *has* to have at least a few different things it can do, otherwise why would you ever specialize in the first place? If every single cold power did nothing but attack Fort and cause slow, you certainly wouldn't want every cold power. Instead some slow, some immobilize, most attack fort, etc. Elemental types having *tendencies* instead of exact templated abilities is better for balance among the types of abilities and is more encouraging of specialization at the same time.
