Nice to see that trend of "Rangers getting the shaft" is back on WotC menu.
1. Deft explorer? Again? really? DM charity feature. One good thing is that you can change it after long rest so it's not that bad.
would 2 expertise at 1st level be too much for the ranger?
Also, why is there no global benefit for favorite terrain?
Arctic?
Cold resistance and normal movement on ice/snow without risk of falling.
Coast: swim speed and water breathing, maybe also cold resistance
Desert: fire resistance and you need only half food and water.
Forest: normal movement in all difficult terrains
Grassland: +10ft move speed
Mountain: altitude adaptation and cold resistance
Swamp: poison and disease resistance and advantage on saves vs them
Underdark: +60ft darkvision
*Urban: +2 languages and 2 skills from: History, Insight, Deception, Persuasion, Intimidation.
2.
Favored enemy:
Add: when Hunter's mark is casted with this feature, it does not need Concetration and there is no spell components.
also, use prof bonus, now Wisdom for usage. Too much focus on tertiar ability
3.
Conjure Barrage; you wont make a bad spell good, by make it a free preparation. At least give it one free use per day. Or better yet, replace it with Fireball. You can refluff it as rain of arrows.
4.
Nature's veils: same problem with Wisdom focus. Use proficiency bonus instead.
5.
Conjure Volley, Now, if this was instead of that dreaded 9th level feature, we would be talking. at 17th level it's OK but nothing special.
One free usage would not hurt.
Edit: Now I have noticed that from others here that Rangers lost cantrips.
Ofc, they did. why should rangers have some cool trick to entertain at campfire. Druidcraft+Elemetalism
Now we will be in a world without Rangers of 5th level casting poison spray instead of shooting someone at 150ft with archery style. Such a waste...
