I suggest that, with all the new worlds and level caps, by the next world or two more powerful spells from the other schools should become availible, such as 7 pip spells. My reasoning behind this is that just 6 pip spells probably won't be enough for very powerful enemies, beyond what's in wizard101 now, and if the only up-to-level spell you have is from your own school, it probably won't be enough. However, the 7 pip spells would be unlocked for more that one training point. I'm sure some people will probably disagree with this, but it's just an opinion.
