As I understand, Requiem also pretty much locks you into one archetype if you want to have any hope of succeeding later - so say goodbye to variety. Someone who actually plays it and dips all over can probably give better statemement on that regard.
It's actually the exact opposite.
If you over-specialize you're going to have a much harder, albeit certainly not impossible, time. Requiem is filled with enemies that have high resistances to different things, enemies that are very difficult to take out up-close, enemies that are very difficult to take out from a distance etc.
In almost every requiem play-through I end up going in thinking I'll make a character of a very specific archetype but often I end up branching out to deal with more situations.
If you're literally putting points into every single skill then indeed it'll be difficult, you do need to make some choices, can't become a master of everything. But if you stick to less than a handful of skills it's going to be just as difficult.
A balanced character, taking the skills that come naturally whilst playing, is by far the easiest character to play. What I've found worked best was to simply not spend your talent points when leveling but keep them in reserve until you encounter a situation where you feel you need more of a certain skill.
My current character I went into thinking I'd make an archer. But in Requiem heavy armor just completely stops arrows from rookie archers. Luckily I had a point in reserve, put it into sneak and slit the bastard's throat from behind. Best stealth kill I've ever made in Skyrim, because it happened out of actual need and arose naturally.
