Don't fall for the "Herald is god" blah.*
I mean unless you like to have boring, passive party members. Your initial idea about going with Wizard/Priest and Druid was totally fine. A herald can be very useful, but in my opinion it's boring to use too many of them.
What a herald can do for your party and all summons is quite nice though: they can combine Shared Flames (Upgrade of Flames of Devotion) and combine it with the chant "Mith Fyr" and the Zealous Focus aura. Both will stack and give all party members +30% (afaik) burning lash for their weapon attacks. Then he could switch to "survival mode" and deliver bonus armor and healing with Ancient Memory and Exalted Endurance. Both can be done parallel with two Heralds, true - but as I said that's also quite boring since it's very passive.
Paladins can't buff as good as Priests, Paladins can't heal as good as Druids (except single allies) nor can they deal that amount of damage nor can they do CC as well nor can they summon anything. So the statement "Paladins can do everything better" is utter nonsense. It's misleading and totally subjective. They can do SOME things better than others. But what a crappy class it would be if that wasn't the case, right?
The most powerful summon overall is upgraded Ancient Weapons, not the Dragon. But the dragon is more impressive.
Also the dragon (and drakes and spore) can be affected by Wild Growth (Ancient Druid ability) which is fun to use. It makes your beast/primordial summons bigger, gives them more armor and heals them.
Priests can be very helpful since the can provide a ACC of +15 for the whole party rel. early and also can prolong all positive effects (how short they may be) with Salvation if Time. This can be very powerful.
All casters (Wizard/Druid/Priest) start a bit weaker because they simply lack spell uses in the lower levels. But that gets better with each level.
Wizard's and Priest's summoned weapons are not like the Chanter's. They will summon them into their hands and fight with them.
With a Chanter you need to pick at least one invocation that has the highest possible phrase cost. Your phrase counter will stop at the amount of the most costly invocation you have. If you only pick cheap ones your counter will not go above them which is bad. It can be very beneficial to have a phrase counter of 6 and then dish out two invocations in a row that only cost 3.
