If 3 named can spawn in a certain area, they are currently on 20% spawn timers every 20 minutes (or darn well should be) or at an equal rate (ie, 10% with 10 min respawn). That's a single named every 100 minutes, on average. So, if a couple of folks found 3 placeholders in a specific area that they were able to keep clear before respawns, they would get 18 named NPCs in 10 hours, on average. That'd be 14 blues and 4 yellows (rounding down on the blues for the sake of your argument).

Those are our HARD metrics; a named spawns 20% of the time when it has a 20 min respawn timer. If there are encounters in the game that are violating this spawn mechanic (and I'm sure that there are...is a bit of a chore for me to dig through data to find em, heh), feel free to PM me here and I will fix immediately after I investigate the validity of the report. If ya feel bad doing it, consider yourself doing the crafting community a favor by making the adventurer actually have to invest time into his/her gear

When the coder was determining the new attribute soft and hard caps a few months ago, he asked me what we did on items so that he could code the caps around it. I, of course, told him no more than 60% of the total points into attributes. He then based the soft and hard caps on that 60% number (so 60% in one stat, 40/20 in two, 20/20/20 in 3, etc...). As such, should items be allowed to have more than 60% total in attributes, it would be a lot easier to reach those caps, whereupon people would probably start complaining that the caps are too low (ie, darned if ya do, darned if ya don't)

Also, something to keep in mind when it comes to the adventuring vs. crafting argument, which seems to be fairly prevalent these days. The most common source of adventuring item comes from the "world drop" loot tables; ie, I can kill any NPC and have a chance at getting a piece of loot. That table is made up of greens and blues, the greens taking up 80% of the table. As such, the most common source of adventuring item is green 80% of the time, a rarity that is always surpassed by any crafter if a dust is used. On the dungeon/named side, 80% of the drops from a "normal" named (ie, not a sub-boss or boss) are blue. This is, for all intents and purposes, the default rarity for crafting. As such, crafting is making items that are at least as powerful as the items that come from the more powerful denizens in our game.

Using the "points" reference above, the average piece of crafting gear has higher "points" than then average piece of adventuring gear. Changes like this nonewithstanding, crafting tends to have access to making gear that is better, or at least as good, as adventuring. Anyways, just attempting to illuminate some things so may have rambled, sorry

60% is the maximum amount of points that any single attribute, or combination of multiple attributes, was ever intended to have spent on it. The actual costing of the attributes (ie, takes X of the item's points to get Y in STR) was built around the 60% max.

Additionally, abilites were tuned around the 60% number, as well as attribute soft and hard caps. Allowing items to have more than that could force a complete revamp of those caps and abilities

It's just a reporting issue on the item's tooltip; % was added in the tooltip so people would know that certain +spell damages were actually +% spell damage. The increased range on ammo just happened to get updated to add a % as well. Will let the coders know.

Vendor-bought Plain Flight Arrow said +10% but is still actually giving +10 to range.
