Question about Rogues

[Crucis]

I have a question about rogues and rogue skills, particularly Mechanics. 

 

Do you need rogues in PoE2?  But the question is deeper than it seems.  It's definitely not about whether you need a rogue's combat skills.  It's more about their non-combat skills.  It appears that the skill system has been changed from PoE1 where after the first 1-2 skill points each successive skill point in a skill cost multiple points.

 

Let me put it another way.  Can you take a Cipher (who apparently also starts with 2 points in Mechanics) and end up with a character who can be every bit as skilled in Mechanics as a Rogue?

 

Just for the record, I happen to be one of those players who loves sneaking through dungeons and searching for traps and such.

So far my rogue and cipher both use mechanics in the same way (sneaking too). Didn't come across any situation where being a rogue made things better. In fact my cipher is the main stealth and sleight of hand guy, while rogue is doing the lock picking and trap disarming.

Ciphers have the same base mechanics as a Rogue, so you can.
