Facts :
Betrayal's root is betray, which comes from the Middle English word bitrayen — meaning "mislead, deceive." Betrayal has to do with destroying someone's trust, possibly by lying.
"true to 5e" and "implementing it as pure as we can" (Swen quotes) : expressions, among other ones, attracting D&D players to sell EA.
Same for working "directly with players", listening to us etc.
Result (factual) :
Hello D&D buddies ! Today I play a warrior. I can heal like a cleric and cast spells like a wizard with my ninety scrolls. When I am hurt in a fight, I eat my bogies and I feel better. My bogies are very abundant, it is very practical. I can fart also. This is a magic fart. When I fart, I avoid what some D&D people call "AoO". And it is strategic too. I can flee with my fart, and I can gain advantage. It is fun. I like advantage. I do not need spells and complicate things to have it. It is good. You know, I just fart. Or I climb stairs or ladder. If my buddy is down, I touch him, and it is ok. Buddy's back. A dozen times if I want. Touch. Cured. Touch . Cured. Otherwise, I throw a potion on the buddy, et voilà. No more need of what D&D people call "healing word". Oh I do not need what D&D people call a bow and a sword. I can cast grenades, powder barrels (it is better than this old and dusty D&D fireball), boom boom, they are all dead. It is very fun. I don't know why D&D people want 100% of rules. What are D&D people complaining about ?
(Of course, it is a limited list)
1) Please point out where a warrior can heal, because I have played the class in game, and the only way (which does a sucky heal because he doesn't have correct stats) is to use a healing scroll in regards to a non-ability heal like pots. Your classification of jump, although you probably believe is hilarious is really kind of childish.
2) You cannot just keep lifting your companions from being disabled indefinitely as you put it, you can do it once per character on your party. So if the PC helps say Gale up during a fight, he can't do it again during the same fight. Another companion has to do it.
3) I actually agree with you about the barrels I think they are idiotic.
4) Lets be honest with 5E here. It is the carebear edition to the D&D franchise. MANY D&D players despise it, and concur that 3.5 is the best. So really, if Larian wants to make some changes to it, that is fine with me.
I keep seeing these posts from some posters, that it isn't about the fact that Larian didn't go 1:1 in regards to 5E, which again if you want to be all elitist about pure D&D would be wanting more 3.5, but about 98.9% of complaints I have seen is in regards to ability sets, or class sets in regards to the strict definition of 5E. Which in all fairness, I feel is ironic, considering that 5E itself basically changed the established rules of the previous editions, so people aren't as locked into their class lol. Not to mention, in regards to complaints of short rests, one of the benefits of 5E over 3.5 is the flexibility and the chance to in fact take short rests.
*And yes, I see the irony of a semi snarky reply in a post about less aggressive communication. My apologies.
