In several interviews the developers had previously said a single character could (eventually) learn all skills, except for other professions and players couldn't be both a vampire and a werewolf at the same time.

Late last year they changed crafting to also use skill points. At the same time it seems they changed their mind about the skill point cap. But they didn't communicate either change very well.

In responses to questions in this forum many still respond "yes there are enough skill points for a character to max everything". While I would like this to be true and the prevalence of this belief makes me think there could be riots if ZO did anything but, I think clarification is required.

From the ESO website:

Will it be possible, thanks to level-ups, Skyshards, Alliance Ranks, and special quests, to gain enough skill points to acquire ALL the possible abilities for a given class and race?

With a game that will grow and change as much as ESO will, this is a tough question to answer! At launch, you won’t be able to max out every skill with the number of points available. However, we’ll be adding more skills and skill points, so it will be fluid. You might not be able to max out everything at once, but you might be able to have all but the class and racial skills, for example, completely unlocked at different times with a single character.

Same page incidentally (same time but different interview), and a bit higher you see them say:

Could a character advance all of their skills just through exploration of Skyshards?

Skyshards help you get more skill points. You still need to gain experience, influence (for the Fighters Guild, for example), or inspiration from crafting to advance and level your skill lines.

They don't answer "you can't advance all of your skills"? Since the question specifically says "all" their response implies that implies you can. So even their own teams a bit confused about this one.

yes you can learn ALL skills they said that already

I think it is the same logic as Skyrim in this case -- One can make every max every skill in that game to 100 with out putting any skill (perk) points in the said skill -- but they will be weak. The real question is, do we have enough Skyshards to put points in every skill or just the case every skill can be "100" but do not have enough skill points to truely max them out?

"At launch, you won’t be able to max out every skill with the number of points available."

I think that basically means you can learn, respec, learn other things, ect, but at no point will you be able to have all your race/class/faction/crafting skills maxed out with full points at the same time.

This was true PRIOR to the crafting overhaul. Now that crafting skills require skill points, you cannot learn every skill at the same time, you can however train them all.

You will need to utilize respecs to swap skills around when you run out of points. So you can LEARN them all, but you can't USE them all at the same time.

This. As it stands now, I believe there are enough to learn every skill if you don't invest any into crafting.

Of course you obviously didn't real the original post.

But you eloquently proved my point.

LOL. So it's literally one step forward two steps back.

Thought I'd check the official site for current info.

Besides other class skills, can all skills be acquired in ESO?

In general, you’ll be able to get most of the skill lines. Class and racial skills are exclusive to your choices. However, there are some mutually exclusive skill lines—for instance, you cannot be a werewolf and a vampire at the same time.

I'd read that as saying yes we can max them all (apart from racials, profession and vamp+ww) though I suppose the wording of their response is a little slippery.

I submitted an "unhelpful" feedback response on this with a link to the statement answering the same question with a straight up no. If I get a response or notice they've changed it I'll post that update here.

So, from what I'm gathering it's going to best to just level up an alt to max out the crafting skills than waste those skill points on crafting perks on your main.
