I was in a nice goat party recently, trio, all of us were Rank 11-12 ish. I was primarily healing. After about two hours, I had earned about 1/2 a rank on CON, while the GLA and ARC I was grouped with had both gained 2 full rank levels. I know that SP for party healing got nerfed thanks to some people exploiting the system, but I think something is broken with SP distribution in a party.
Can anyone confirm or deny that the potential for SP is capped per fight? If there is in fact a cap on potential SP earned, is it based on the rank of party members, number of party members, level of mob? Does dealing more dmg earn you a larger portion of the SP available in that fight? It seems that I bust my a$$ healing and chat log reports a decent number of skill ups, but somehow those numbers aren't hitting my rank xp bar at the end of the fight.
After observing this trend (and painfully typing out to my party what I was experiencing) I switched up my combat tactics and started spamming "1" (Spirit Dart) a lot more. Low and behold, for the next 30 minutes or so of parsing, I was earning SP at approx the same rate of the GLA and ARC.
Why would anyone want to heal a party and earn a fraction of the skill xp?
Here's another problem from a healer's perspective.....to effectively heal (at least as a lowbie), I utilize both Sacrifice (THM spell, direct heal + HoT) and Cure (CON spell, direct heal). When I'm playing as CON it's impossible to gain any SP from using THM spells like Sacrifice and when I'm playing as THM it's impossible to gain any SP from using CON spells like Cure. The SP mechanics actually deter you from effectively healing a party.
