Overall, they actually got worse by comparison. They maintain their utility with the special arrows, but they don't do anything that a wizard won't do better, really.
Since special arrows are now fired from the knees, they also have a tendency to snag on everything in the world geometry. With the addition of grenades, although a great addition in it's own right, this utilitarian role is further diminished in value.
With the nerfs to rogues, guerrilla and the sneaking skill, rangers are worse off than pre-EE.
Pretty much this.
To the point I don't really have an idea what to do with my char' in Tactician. Keep going Marksman and hope for the best ? Try to switch to Scoundrel[rogue] but it may be even worse ? Switch to full wizard ( I'm not a big fan ) ?
Essentially the game now asks and push for heavy specialization. Even with lone wolf it seems hard to keep a bit of multitasking and remain useful.
