When combining different elements in a logo, you run the risk of making the statement of the logo more imprecise. Hence you should weigh up which elements are necessary, and which elements degrade the statement.

Creating a logo with a text part and a figure part is not a problem, nor is it a problem if the figure part consists of several parts. Also, the text part may consist of the company name and a slogan, for example. However, you should take look out and balance if all these parts occur in combination.

Maybe it is better to not "load" logos that are made up of many stilystic elements with lots of text.

That can't be said across-the-board, though. You should weigh up yourself if something is overkill or not. There are lots of very simple, good logos, but on the other hand there are also complicated logos that are nevertheless good.
