I'm aware of what is needed to raise a new character, and did recently make and raise a new character's stats just to test it out. I was able to fund tria from my main of course, but you can't hand over pp, and my experience was that pp is actually quite easy to acquire. Maybe more rebalancing is still needed, because of course I can't help but compare to how much pp was needed before the last big set of changes to skill/stat training, but I would say the difficulty curve in terms of affordability has definitely been moved in the right direction and, more importantly, if there are still problems it should be directed to the devs, not left to the GMs to address in events. The GMs can't get at or fix the underlying cause of these kinds of issues, and events often can't run often enough to make a big enough difference for enough players for something like this.
The problem with rewards really does link back to where Lumi quoted me again. More pp might make you happy and some others happy, but there will also be players who laugh at receiving it and find it 'unfriendly' just as you feel only receiving tria is unfriendly. I've seen people get annoyed even when they receive both. I have even seen players laugh over and insult the reward items. Very very few players ever actually say 'thank you' or 'I appreciate that', or seem content with what they get in any way at all. A few only seem happy if they get some super rare reward worth millions. Sooner or later you have to draw a line on what is or isn't fine to give.
We also have to think about those who can't reach events due to timezones. It's not fair to give a big boost to those who happen to play at the right hours to be able to attend events. Then those who can't come would have to watch others shoot ahead of them in terms of tria/pp/rare items. If 1k pp would be a big deal to one person who attended, it's almost certain that someone else would have found it a big deal too and will be upset they missed out. Which isn't to say pp won't ever be rewarded, just that it shouldn't be an assumed automatic reward.
From a personal standpoint, when I run an event or am one of the ones involved in running one, I like to give things out and I try to make it somehow appropriate to the event itself. I also try and make sure that the rewards don't always go to the few players who are almost always the most visible RPers. Those people might get rewards, because they give us something to respond to, something to work with during an event. But so might people who do something surprising or that impresses us in some other way.
Also please keep in mind that preparing for a large event like the ones that have run recently often takes up a few hours time for each GM involved before the event even begins. I'm sorry if a reward seems 'stingy' but the reward should be taking part itself and getting to (at least sometimes) enjoy things that can't be experienced without GM intervention (morphed characters, areas of the map you can't usually reach and so on....)
Gonger - I'm not sure who you might need to speak to about this. I think something like this does need to go somewhere though.
