Defense only needs one thing now

[Babyfark McGeez]

With the "Reinforcements needed" spawn spots and the improved base design (that could be further refined, but imo has the general idea right) defending has recieved some well-deserved attention.

In my opinion there is only one thing needed to make defending a perfectly viable option for both ("casual") solo players and coordinated teams:

A static XP reward once you successfully defended a facility.

Because the underlying defense-problem still is that "15% more xp" of 0xp is 0xp. And 250/500/1000 xp guaranteed is still 250/500/1000 xp guaranteed.

The solution here lies in making the one-time xp-reward more dynamic, and this system should be applied for both the one-time attacking reward and the one-time defending reward (as suggested by psijaka).
Base it on the time factor, taking into consideration how long you personally have been there AND how far the capture bar had allready ticked down the most before it started being resecured.
Also scale it according to the numbers of actual attackers/defenders, as in "more opposition = more xp" (as suggested by Canaris).
And regardless of defending or attacking reward, maybe even factor in the overall duration of a fight (with back and forth capping and resecuring a full capture/resecure can take quite a long time).

The result would be that even an unskilled defender who has not the prospect of making lots of xp with only the "%" bonus on actions will have a (fair) reward for (successfully) defending a base, and thus a motivation to do so.
