Moon school currently kinda sicks. Lets face it. Polymorphs are useful in very few situations and currently is more of a gimick than a useful tool. There needs to be some rework done here, I think that this could be done by removing the turn limit from polymorphs. Make the cards cost ~5 pips or so and have actual fleshed out decks. Once you die as a polymorph, your pips are reset and you return to your wizard self instead of losing. There could be some sort of backlash or health loss mechanic to make it more damaging to keep using them. But with this change they would have a good use and with proper balancing could be a great tool. There would be an actual reason to train polymorphs.
Sun school is in a good spot right now, alhough I feel that they could make some creative spells. How about enchantments to give a spell pip mastery? There are mutates but this could be 110+ and useful to higher levels. Maybe an enchant to make a spell unblockable (enemy can't block if it goes critical)? I think there is a lot of potential here to make interesting mechanics.
I think this school is very well developed as is.
I'm interested to see the direction this will go, it seems to be well developed so far but I would like to see more shadow spells available. We should be able to learn shadowblade/trap/shield for example.
CRITICAL SYSTEM This system is in dire need of rework, and its obvious. Critical availibility shouldn't decrease as you level up, it should increase. It should be rare for a lvl 50 to be able to critical, even with good pvp gear. Theres a lot to be worked on in this system in general.
PVP 5th age should not allow pets or TC; TCs have become too prominent and removing them in PVP would actually level the playing field somewhat. It is just stupid how much they are required to succeed in pvp at lower levels. Pets have become more and more powerful and shouldn't be usable in PVP either, there should be focus on attaining good gear for pvp but the pet grind is a big wall to many users. By removing these 2 things pvp will be a lot more fair and although there would still be pvp Gear, the grind to do well in pvp would be less crazy and more strategy based.
GEAR META Darkmoor/gauntlets still have the best gear in the game. Lvl 130 gear should be better than lvl 100 gear, so hopefully new gear will be added with the next update. Pip conversion is an interesting mechanic, but it is not very useful. There was a good buff to it but I feel like it is used in place of much more important stats on newer gear. The revered wands for example would be much more useful if they offered 50% stun block rather than pip conversion, (or maybe stun block or another feature in place of fishing luck??)
MISC -An account should have 7 character slots, we all know why there is only 6. Come on. -name/character changes should exist, even if it only costs crowns.
