I haven't been in the arena for a while now, so excuse me if this is outdated.
It'd be nice to have a corner, or corners, built into the arena so that non-SD-phasing rogues can use their tricks. (A large pillar or wall segment in a corner or corners of the arena pen)This is useful with pen's ideas for combat training schools, it enhances the opportunity for things to teach outside of 'Let's charge hasted and spam f1 IKD'. It also supplies opportunities for melees to fight a caster with some semblance of a chance in combat.
Anything that casts a shadow, most often a tile pillar or wall segment would do the trick (I find placeables to not cast shadows most of the time).
This, of course, can be abused in a true PvP situation by cornersneaking over and over again, but that's on the long list of unbalanced or abusive opportunities to the myriad skills, classes, spells, or feats the game offers in PvP scenarios. And it's at the bottom of that list I'd contend. Regardless, true duels set rules.
That and the main idea here is RP enhancement to offer more combat situations and flavor to the arena.
Anyhow, just an idea.
