When doing the L95 daily task from franklin teek , the task kill 5 sharks in sarith city of tides , only gives 50% of the rest of the L95 tasks.
Can't confirm, purportedly both L90 and L95 give 4% exp at level 95: https://everquest.allakhazam.com/db/quest.html?quest=6875 https://everquest.allakhazam.com/db/quest.html?quest=8826
It's been a long time since I did Teek tasks, but at one point certain tasks were worth more experience than others in a given level group. But it has been so long since I delved into the Teek world, that it's just a vague memory. I assume that's what the OP is talking about.
If you are counting the mob kills and not just the reward exp, and/or it scales to the zone level, Sarith is a lower level zone than Pillars and Temple so it would make sense its by design.
This is just reward xp , reward from the 3 pillars 95 tasks is 7.5 ish aa , reward from the 3 resplendant temple 95 tasks is 7.5 ish aa , reward from 2 of the 95 sarith tasks is 7.5 ish aa , but reward from killing 5 sharks task is 3.5 ish aa
