When a Cleric or a Paladin gets an advanced domain, they increase their spell point pool by the amount of points it takes to cast the associated power. In theory this is helpful to ensure "you can actually cast this" but since Power 2s vary from costing 1 spell point to costing 3 spell points, doesn't this serve to effectively encourage some domains (e.g. zeal, travel, freedom which have 3 point powers) and discourage others (e.g. death, air, fate, which are 1 point powers). I mean, presumably everybody with a spell point pool would prefer to have as many spell points as possible.
Like a Paladin of Iomedae can select Zeal twice to get 1 extra spell point from Weapon Surge and 3 extra spell points from Prepare for Battle, and thus be able to Lay on Hands 4 more times, but Pharasma's Clerics are much less fortunate as 3 of their 4 advanced domain powers cost only one point (and the other costs 2). I see this as effectively incentivizing Pharasman clerics to snag the Healing domain over Death, Fate, or Knowledge because it gives an additional spell point if you grab both powers.
So should advanced domains give the same number of spell points no matter what you pick?
This is a good remark. I suspect this difference between domains may be due to the restricted size of the playtest rules. In the full game, there hopefully will be room for more advanced domain options. So, every domain could (should) have 1, 2 and 3 point options to pick from.
