That's your problem. I require actual evidence and not hear-say, especially from someone I don't know about and is making some absurd claims that go against established evidence.
False. Blizzard is not using the RPG books as a source of information for their game. You're making literally a
baseless assumption that flies in the face of
actual information from the developers when they stated the books as non-canon.
The World of Warcraft game has no examples of tinkers being better than engineers or vice-versa. You're literally making shit up.
No, they don't. Not only the rpg books
do not make the distinction, but the RPG books are
useless to determine lore. Either cite some official source or show me in-game examples of one 'type' being better than the other.
Show me the evidence. Like I said, I don't accept hear-say from people that like to make nonsensical claims.

Which is meaningless because those examples don't show any difference between the two terms. For all we know those could just be synonyms, like "mage" and "wizard".
I noticed the "player"s name is not being shown. I don't feel like jumping into island expeditions just to look for them again, but I'm pretty sure the person that made that video named his character "tinker", and player spawned constructs are given the "title" of "<player>'s construct". Do you have any screenshots of how they actually look in the game? Neither show as having any titles in WoWHead, and the site does show NPC titles:
Keep in mind that WoWHead does not show titles such as "<player>'s minion/companion/guardian/etc" in their listing. And the idea that "tinker" is just the "player"s name is further reinforced if you rewind the video and look at the 3:45 mark, the Heal Bot is titled "Tinker's Guardian", and further rewinding the video shows the turret being called "Tinker's minion".
Other than that, it doesn't really mean anything to disprove the idea that "tinker" and "engineer" are not synonyms.
Irrelevant. First because Hearthstone is not canon, and second because what you wrote doesn't mean that.
