If you wanted to address this mechanically, how would you do it?It can get trickier if there are other effects that clearly follow the keyword - eg a Cold power that inflicts Slow. If you make that into a Fire power instead, does it still Slow (how? why? clearly it's not freezing anyone anymore) or (say) cause OG 5 Fire?
The way I see it, there are two approaches. You could either have a codified list of damage types and linked conditions (cold and slow, fire and ongoing damage, radiant and blinded, thunder and deafened), and then say that swapping out the damage type also swaps out the corresponding condition. Or, you could get all vague and just leave it for the DM to figure out, with a note that you should change the effects wherever it makes sense.
The first solution seems more likely to cause unintended consequences (e.g. if it's easier to slow a group, because slowing isn't as bad of a condition, and swapping it to ongoing damage or deafened would make it too good), but the second solution isn't very satisfying either.
