RED update thoughts and feedback

It appears that there was a game-wide spawn increase, yes. Though as far as I can tell, outside of low and high level characters, your best bet for EXP is still Extreme MP/Invasion/Evo.

The best training spots definitely wouldn't change; as you said, it's a game-wide spawn increase. However, "spawn-increase" isn't quite the best way to describe the change. The time it takes for monsters to re-spawn has been drastically reduced, leading to monsters spawning before you can do a full clear on a map. No extra monsters are spawning, afaik, they just spawn faster. That means no more waiting between spawns in things such as DI and Evo, so clear speeds have gone up considerably, as has the exp gain. Such a small change that makes the game so much more fun, especially for people who tended to clear extremely fast before the change. Now there is a bit of a challenge for my low-funded characters in DI, especially on that last tower.
