@Aelobin That is to say; the squish won't affect soloing capabilities, but other changes may. Soloing at low levels isn't a balance focus.- Celestalon (@Celestalon) January 7, 2014
What Chadd doesn't do is expand on just what exactly these "other changes" might be. At a guess, I would imagine that they may relate to ability changes, as there is a planned sweep to address the issue of button bloat, so you may lose some of the skills that you currently use to solo older content. Perhaps it relates to the non-linearity of expansion transition gear, or perhaps it's none of the above. Nonetheless, the message regarding the item squish is being received loud and clear.
