Well, I have not tried these skills on test center but I do have quite a few thoughts so my comments are based on the descriptions given in UO Herald.
First is that I think it's great the the developers appear to have taken our comments seriously. We asked for songbooks & buff/debuff bard spells and that's exactly what we got. I've also seen other requests from players that have been added, such has removal of the runebook delay and changes to the throwing skill. I'd like to say thanks for listening, it's much appreciated. Now, onto the changes as they are currently proposed.
First, I really don't care much about the quest required to gain mastery. Truth be told, most of the bards I know are serious long-time vets who have spent countless hours fighting the toughest creatures around. Add in that bard skill are quite difficult to level up, and I really don't see any point in wasting too much time and effort to get mastery skills.
I think it is ridiculous that you can only choose one path of mastery. Please, please, please change this. Simply put, there are different times when each of the skills would be more useful, and it's just silly to have to go through the quest again each time you want to use a different mastery skill. For example, sometimes you hunt in a party, sometimes you hunt alone. Sometimes you hunt big dangerous creatures other times you hunt masses of small creatures. Based on the descriptions, I think the different skills can be useful in different situations. Just make it so only one can be active at any time. I'm gonna ask again. Please, please please please please please please change this. Please.
Again, I haven't tried myself but I'm glad the songbook doesn't need to be held to have an effect. I have armor suits & equipment designed around stuff I need to hold already. I play a bard/mage (slayer spellbooks), bard/archer (bows of course) and discord/tamer. So, based on the description, I'm glad you don't have to hold the book to activate mastery because it would force a bunch of changes.
I'm concerned about the "maintenance" that they talk about. Like, it's gonna require continuous mana use to maintain the skill? That's gonna make it a lot less useful for my bard/mage & bard/tamer because those templates can sometimes use considerable mana already. For bard archer, no problem because I leech mana. Need to test to make sure, but onerous mana requirements will make the skills near useless.
Despair debuff does 20-60 physical damage every 2 seconds. Is that before or after physical resist is calculated, because a high resist foe will only be taking like 15-20 points of damage max every 2 seconds. Not much when compared with 150-250 every 1.5 seconds from an archer. Which leads to the question...
Which of these skills can be used in PvP. Certainly, some of the party buffs seem like they would be quite useful in PvP. How about the despair debuffs. Guess we'll just have to test it out, see how it works.
All in all, I'm excited. I'm looking forward to trying it out, and certainly there will be balancing issues. But please please please please please please please, allow bards to train for any mastery they qualify for. Or maybe have something akin to stable slots where you can qualify for additional masteries when you have higher total skill, or something. Doesn't need to be overpowered - just one skill active at any time. But allow the bard to have a choice when different situations present themselves.
