Oldies but Goodies - A Few Beta Ideas

I thought I would link to some old ideas from Beta that never made it into Vanilla for some reason.  ^^   Unfortunately I can only easily vet the ones I replied to or made, and it's kind of a random selection, so if you had an awesome idea 7 months ago and you don't see it here put it in the comments

I figure we will see new maps and new DGs from the community and from the devs, but there are some small tweaks to mechanics below that could really make a huge difference..

http://forums.demigodthegame.com/334754 - get around the map hardcoding by introducing buildings that alter line of sight - allows true ambush and evasion

http://forums.demigodthegame.com/325001 - Crazy Items - reduces competitiveness but would be a fun mod - actually 70% of the items and their prices could use some work

http://forums.demigodthegame.com/337831 - completely obliterates rationale for the current minion system and has a good system to replace it

http://forums.demigodthegame.com/343071 - shield mitigation increase proportionate to damage

http://forums.demigodthegame.com/342855 - items affect spell damage - could be very cool if done right

http://forums.demigodthegame.com/342065 - citadel upgrades renovation

http://forums.demigodthegame.com/348288 - immunity (like with stuns) should apply to all spells (including buffs)

http://forums.demigodthegame.com/345538 - various random post-release ambitions (including some from Frogboy)

http://forums.demigodthegame.com/323546/ - innociv's ancient and still awesome Combine Items post

What other ideas can we throw out there for the future?  To clarify, I'm not expecting GPG to make these changes, but anything they can do to allow *us* to make them would be excellent
