Even now, as I write this, DBM has exceptional mods ready to go for mythic+ dungeons and mythic Uldir up through 8/8, with mythrax and ghuun having as best support possible with limited pull data and datamining available.
In Mists I was able to switch to doing it full time and greatly improve the quality and feature of mods as well as pace that mods are released for content. I have been raiding in wow since Burning Crusade and been making mods for DBM since Wrath (almost entirely by myself mind you).
Every mod puts careful thought into what the best voice for an alert is that clearly and concisely advices action based on warning.
Load on demand - all boss mods are separate AddOns and they will be loaded when they are needed.Modular design - all boss mods are plugins and can be exchanged, removed or updated separately.Infoframes that is used to show fight overviews or specific mechanics related to fight to help give you need to know information at a quick glance.Crash/DC recovery: you had a disconnect or crash during a boss fight? No problem for DBM! It will request the timer and combat status information from other DBM users in your raid group and you get your timers back.DBM aims to help you process these bars at a glance. Bars that not only show time remaining, but make use of colors and icons to show what type of ability is coming and what role it's for.Bars can be enlarged with custom effects when they are about to expire.
This feature is completely optional and can be disabled by player or even raid leader for the entire group. These messages contain the name and health of the boss as well as the raid's status. DBM will inform anyone who whispers you during a boss fight that you are busy. A big focus on filtering/hiding what you don't need to know for your role (or what you can't do anything about such as dispel/interrupt on cooldown), so you can focus on the information you do need, while also maintaining ability to disable these filters for leaders that do want a larger overview of fight events.DBM aims to let you know what to do for something, not just show you a spell name. Colored raid warnings (players will be colored according to their class) with icons and to the point messaging.
Mods for raid, dungeon, special event and Brawlers Guild.
