First off, let me take my hat off to Obsidian for introducing Turn-based mode. You guys are awesome!
Now, apologies if this has been talked about before, but ability duration, as it currently stands, seems a little messed up. More specifically, every short-term ability now lasts a single round irregardless of its original duration in RTwP, leading to at least three kinds of problems
1. Very short term abilities (5 seconds or less) are now much more powerful. For instance, the Shieldbearer's Lay on Hands can now keep anyone alive indefinitely so long as the paladin has zeal left. It is also now very easy to disable-lock enemies, thanks to the abundance of fast-casting 1 round disables. Also, correct me if I'm wrong, but I believe Brisk Recitation now gives you two overlapping phrase effects due to the 1 round minimum duration of any effect.
2. Moderate-short term abilities (around 8 seconds) seem unjustly nerfed. For instance, Glorious Beacon now has a 1 round base duration, making it very difficult to use in conjunction with offensive abilities (I'm thinking of Heralds here.) That is, unless the character has an extremely high INT score, which leads me to my third point
3. Having stratospheric INT is now a prerequisite for many classic multiclass builds. Take this popular Herald build which relies on casting Inspired Beacon followed by the Seven Night She Waited invocation. This wasn't difficult to achieve in RTwP - all you needed was 15 or so INT and the two abilities would overlap. In Turn-based, however, you need at least 20 INT to bump Glorious Beacon into the 2 round range, and I'm still iffy whether this is enough for the combo to work effectively.
What do you guys think? I'm sure there are a lot more points to be made and examples to be brought up.
