PRO:

• free stock images of some D&D maps (can't really complain about that)
• great reference for usage during games to give players a visual idea of where they are fighting
• well done artwork makes the visual references easy to understand
• don't worry about the names of the locations - just put these anywhere. It takes a lot of the work out of (small) dungeon-building

CON:

• the artists aren't credited (this is surprisingly, frankly, because crediting artists is just good and responsible business practice)
• there are not many images in a pack usually, but this is an exception (but you can't really argue with free)

PRO:

• free stock images of some D&D monsters (can't really complain about that)
• great reference for usage during games to give players a visual idea of what they're fighting
• well done artwork makes the visual references easy to understand

CON:

• the artists aren't credited (this is surprisingly, frankly, because crediting artists is just good and responsible business practice)
• the monsters are mostly all out-dated and often unusable except as skins in 5e

PRO:

• free stock images of some D&D monsters (can't really complain about that)
• great reference for usage during games to give players a visual idea of what they're fighting
• well done artwork makes the visual references easy to understand

These were really fun. I use them to give to players, but I also used one for Lost Mines of Phandelver for the shrine in the main town. I used it as a kind of substory quest, originating from the shrine and connecting to the banshee encounter.

PRO:

• I love this. As a DM coming from 3.0/5, this info and concept is really neat and helpful
• helps empower the DMs to make their own decisions
• creates a habit of checking rules that aren't necessarily in the DMG (this led me to join the FB DM group, which has been extremely beneficial)
• the quests are intriguing, if not necessarily enjoyable in and of themselves
• encourages good practices/being a responsible DM
• good updates to general questions, in general (eg, ending treasure for season 6 WPM)

CON:

• some DM quests are too limiting, reflective of only a small population abusing the rules (eg, dedicated DM)
• some DM quests rely too much on repetition and fulfillment of uninteresting activities (DMing should be interesting too!)
• some DM quests rely too much on advertising for WOTC (eg, Ritual of Divination/Scrying). I don't want to advertise for WOTC
• not enough DM quests
• not enough rewards for DMing (eg, compare DMing versus playing WPM)
• not enough incentivizing, especially if someone prefers DMing over playing but still wants to keep up with their friends
• DM quests/starting items shouldn't end with each season because that punishes DMs for coming into 5th edition later than others. The rewards and items are not powerful enough that they're extremely abusable (eg, starting with 300GP and getting a secret mission after finishing WPM with my players (two separate examples) is not game-breaking. Moreover, ending the DM quests with each season deincentivizes running past modules and hardcovers
