Oops, I wasn't using completely full necro but with 1 pt in geomancy. However, I was seeking to specialise mainly in necro and spend time debuffing characters.
Of course you're supposed to use skills in conjunction with one another. And I understand 'cos primary witch in DOS1, was always debuffing and then secondary skills for attacking or healing and so on.
As it is:
Things are too rigid atm: you can't mix it with another class freely. It has to be scoundrel or some other specific class.
'Cos it's supposed to be classless system(unless Larian wants to nuke it), so they may want to tinker the effects so that other classes or talents can take advantage of it. Like people mixing necro with lvl 7 fighter(1 to 2 points in, just for minor debuffing on their own) and so on.
And if people want to play main necro, let them take it on if they're willing to accept the handicaps/limitations. Didn't people play what? Witch mixed with scoundrel or geomancer mixed with fighter(they just didn't take on leech or Picture of Health or some other talent).
Larian, please keep the true spirit of the classless system. :P
