While the soldiers were handling the teams' leaders (the elementalists), the rest were handling the rest of the fighters.
However, the current Alterran teams were still struggling because the people following the elementalists were at least level 20, which was far beyond the average in Alterra.
For now, there could only be a maximum of three Alterrans handling one enemy so it was, understandably, quite the dire situation. It was not a surprise that during the past couple of minutes their leaders were fighting elsewhere, a few Alterrans had gotten injured already.
