Well, I have been around since February of this year, and I am nowhere near maxed out on anything.I was not around before a lot of the grinding stuff was added, but here are my thoughts on the current implementation:
I like the system in place for training. Find a trainer, train, practice, lather, rinse, repeat as desired. I do not like systems where you can simply respec your character and have them be awesome with a hammer, after only using a sword for the last 30 levels. I don't really know how I feel about the whole progression points thing, as the best way to gain them are from fighting, and after a month or two, you have more pps than you will even use.
As to the training itself... it is boring and tedious at best... and painful and costly at worst. I can finally smelt plat, which is nice, and is one of the few skills that will pay for itself rather quickly. However, my wrist hurt quite a lot after the week spent gaining the last 20 levels required to do this task. I tried stopping when I could smelt gold, but nobody was mining gold regularly, and so it wasn't helping me earn trias at that point. So I borrowed trias from a friend, learned to smelt plat, and was able to repay the loan quicklly as there are always people at the plat mine. *** side note, I am continuing to train plat and noticed that I only get practice points when I melt the ore, not when I cast the ingots... but I still get practice for both melting and casting steel ingots... I have to assume this is a bug and will be checking the bug tracker later today ***
I have yet to see a single level of magic be able to recoup the cost of training it. I agree with prolix here, the benefits are so limited that unless you recite a low level spell countless times to progress, you are not likely to do anything significant.
I have also taken up crafting of weapons... which again... has yet to recoup the cost of even a single level. Nobody wants to buy the lower quality weapons, but this takes the longest to train of anything I have tried to date. I end up giving away most of my weapons to new players just to give practicing my skills in crafting a little meaning. If i have to buy steel ingots, usually costs around 1k trias for 1 steel stock. A sabre requires 1.2 steel stock to make... but I can only sell the finished product to a NPC for 168 trias... I cannot even recoup the cost of materials, let along training this way. The last level I gained in sword making (lvl 14, so relatively low level) took me an hour and a half to train. I set vlc to always on top and watched a movie while mindlessly clicking the anvil to train. I do not know if this is a chicken and egg problem, but nobody engaged me in conversation for that time either. I kept and eye on my main tab every time i gained some pps, and would have been grateful for some conversation to break up the monotony...
As to travel, I couldn't agree more that it is long boring and tedious... and does not allow someone to chat... except maybe via tell, group, or guild chat areas. Unfortunately, every time I have tried to suggest speeding up of travel, in almost any way imaginable, I get told by other players that it is a settings killer or no. Devs have not really chimed in on these discussions, but questing takes an insane amount of time, as does training at higher levels because of the distances involved to fulfill the current demand.
I am not asking to be able to be the best <fill in the blank> in a few minutes of game time, but I do ask that as things progress, that there is more concern given for wear on the players wrist/mouse, and that training tasks are not so mundane and monotonous.
