I meant attack powers like the Athasian Minstrel's
Fever Poison; it's level 3 and has "upgrades" at levels 13 and 23 that improve its damage. Sorry for my poor wording there.
Now that I look at the new themes again I do notice that there is scaling damage on some of the powers. The thing I'm really missing is the option to swap
attack powers of higher levels with theme powers, AKA the Dark Sun style. So my complaint is basically that they're mechanically different to the original themes, with an additional dose of power creep and a decrease of options.
Order Adept really stands out as being too good compared to the other themes. I find this lack of balance disturbing. How could the editor(s) not catch that before publication? It's not as bad as the original battlerager, but still...
Ah, right. I think the upgrading damage options do a pretty good job. Swappable higher level options would be OK too. I get the impression the main goal with the newer content is to keep things simple, less powers, less feats, more fixed options and just generally less crunch.
My ratings would be-
Alchemist - This seems like a nice target for a theme. Doesn't do a LOT for you in terms of combat encounters, but certainly handy. I like the 'thematicness' of it. Power-wise this does seem like about the weakest theme mechanically. I really like the way it reinforces a cool character concept.
Animal Master- I like a lot of the same things flavor-wise about this theme as the Alchemist, it is a decent way to add a nice facet to a character. OTOH I'm not really too convinced mechanically. The animals have the same issue that old AD&D style familiars did, they're going to be toast real fast. The fluff tries to downplay the problem "Oh, the DM should pretty much ignore the animal, it's just an animal" but of course there is at least one power which encourages the animal to be adjacent to the character. The first stray blast is going to crisp Fido up good. That aside the mechanics are OK. Like the Alchemist they don't add a lot of oomph to the character, but a little bit of this and that is OK and fits with the theme.
Order Adept- This theme is on a whole different power level than the previous 2. Argent Rain is a quite nice encounter power, vastly more mechanically significant than what the other themes get. Both features are excellent, again distinctly better than the other themes get. A total +4 to Arcana and +2 WILL!!!??? is pretty impressive. Heck, some PPs barely get better features than this theme. The utility powers are nothing earth shaking, but any of them could be quite useful to some builds. The main thing though is this seems more like a boost to wizards than a theme you'd take to add a new dimension to your character. It just makes you better at what you already do, and it is hard to see a non-arcane character taking the theme (though it could be useful for some divine PCs).
Apprentice Wizard- This one at least is toned down compared to the Order Adept. The features are nice, but not as flat-out hot as Order Adept's. The same is true of the powers. Disappear and Winged Step honestly seem pretty useless as you can get equivalent effects with existing wizard utilities. Minor Polymorph is really the mechanical gem of the whole theme. There's no problem with this theme, except that it simply pales by comparison with Order Adept. I'm not really sure what about it says "apprentice" either. Seems like a cantrip would have worked well here....
RP-wise these themes all work. All I can say about Order Adept is that if I were to have a player using it I'd feel a bit compelled to rake them over the coals some via their order membership. Like most WotC 4e offerings this is a bit of a mixed bag. There's a chunk of good, some meh, and a dab of the not so good.
I'd just note I don't know that the people playing in my current game would really even bother with themes. I can definitely see the attraction, got nothing against them, just not sure 4e really NEEDED them. There such a vast number of customization options already. But ah well... I'm sure we'll do something with them.
