Guild Wars 2

To give an example by what I mean first.

Lets say we have Tier 1 organized zerg vs zerg against a fully upgraded keep. Rewards for when the keep is taken could get based on how many upgrades it has and how many defenders and/or utilized siege count while also taking into consideration the period of time that it has been held by the current owner along with how many times it has been successfully defended. A lot of these things are all ready tracked to a certain extent so I don’t see this requiring much in the way of new tech.

When successfully taking the keep the reward chest from either the lord or daily-reward-chest-style could have additional items/crafting components/currency/rare skins/things possibly normally found in pve etc.. as a reward. The quality, item types, or number of items awarded adjusted of course based on above mentioned factors.

A scaling reward system like this for keeps/towers/camps could help fill in some reward gaps that WvW lacks against say PvE.
