If you want to melee AND cast, Land Druids would suck. It's better to think of them as casters and gear/talent accordingly, with the option to equip a shield that gives some dps and ample utility (wildshape).
One level of wizard helps immensely to provide spammable spells while you're concentrating on something else, and to that be sure to look at selectable spells closely: the there's a misnomer on of the "Extra spell" sets that says you get Call Lightning automatically learned but it's actually lightning bolt.
My solution was Max Wis and elemental adept in either cold or lightning, and war caster.
Pally/Druid would be an interesting battlemage variant but you lose some great spells doing so.
