There is also this rule we like to call "level-adjusting"
The 4e DMG makes it pretty easy to add or remove levels from a monster. If the DM is concerned with grindy monsters, lower the level of the foe but don't change the appearance.
For example, the PCs stumble into a Shadar-kai camp. The first few combats might be against de-leveled shadar-kai warriors, but as the PCs enter deeper into the camp, the levels raise to the MM defaults (and perhaps higher) making each fight a little harder, more taxing, and dangerous. To the PCs, it just feels like the shadar-kai are wearing them down and improving their tactics. Eventually, the PCs reach the turning point; slog on through longer (and perhaps grindier) fights or back off? The DM has accomplished a sandbox feel while keeping combat un-grindy.
The trick is to divorce the "monster X is ALWAYS Y powerful" notion ground into us. Trolls don't all have 7 HD. Goblins aren't always 7 hp monsters, and today's boss battle (ogre) is tomorrow's minion. While this can be taken too far (I don't there is a level 1 Orcus running around, and dragon do grow in size as they tier up) it can create a feeling of "in those mountains there are giants" without forcing your PCs to face level 9 monsters the minute they step into the giant "zone".
