To get better you have to gather experience. This whole “achievement hunting” rhetoric is really nonsensical.

[quote=Savo]Why go through with this whole system?[/quote]
Because I want to? 

Essentially every GM has the choice of how to make the framework of their game, and with something roughly based on a MMO concept this becomes much more important. I wanted to go with something different than the other options, and I believe individuals like [@NarcissisticPotato] understand the general idea quite well. I will say this though, you are trying to deconstruct and criticize the system at every basic level— every loophole, or off-worded comment and it sets a worrying precedent. The focus should be on the characters rather than making sure a mechanic is 100% perfect. That won’t happen. You could easily criticize a normal levelling system with the basic attribute framework, but none of us did that with the previous interest check. We took the basic concept as fine enough and got to work on ideas for characterization.

[quote=Savo]Anything can be used as a weapon y'know. A player could make a trap, lure a bunch of monsters into it, and blam, 100 monsters down. Their trap is their weapon and the only effort they put forth is constructing the trap, luring the monsters, and they are finished. However, you might denote this as almost unrealistic.

If that won't work, what's stopping them from building a catapult or ballista? With that machine, construct, launch, kill enemies, profit, boom, 100 enemies flat out finished.[/quote]
This is one of my central points in the central paragraph— you are trying to look for loopholes. In tabletop circles this would be known as “rule lawyering” and it is extremely frustrating to those running the game to run into this. “What if…” is tiring— and not all that constructive by my view. 

[quote=Savo]So I'm going to think since there are probably dungeons in this, you can most likely party up. What's keeping someone from weakening a monster significantly and then letting their friend put out the final blow, effectively crediting them with slaying 100 monsters. How are they even better at slaying monsters? All they just did was let their friend beat it up until it was significantly weakened before landing the final blow.[/quote]
The flaw with this presumption is you are assuming that neither individuals will be credited for joint efforts— a traditional party system shares experience, so I’m not quite sure why you think that suddenly everyone is on their own even if they work cohesively with a party demographic.  

[quote=Savo]With enough time and effort (a long time and effort, mind you xP) you could effectively turn your character into a jack of the all trades, master of all.[/quote]
Which would be a non-issue for the RP.
