100% agree. Lexa's army may have had more difficulty just because Clarke was able to enter the mountain because Bellamy was already inside and he had a key to open the door to the reaper tunnels. Bellamy would have had to pass that on to one of the grounders he freed for Lexa's warriors in the tunnels to get through.
