No they are not
One needs to have a balanced hanger for fun gameplay. I play mostly against bots and win almost all of my matches, and lose only in rare cases. All my mechs are 4 star level 7 (legendaries). my weapons are 5 star level 7 and pilots are 5 star level 7. My SP is between 5K to 6K, mostly 5.8K, and the bots I face are between 5 Star Level 2 to 6 Star Level2, but mostly in-between. I win all of my matches. When I play with human players mostly I win but if unlucky I can lose too, like being sniped by bots or not playing very seriously, But almost all of my matchs in the battle logs are victory. Though I use good weapons like Gemini and Overdrivers and Revokers and don't like to change very often because it is tedious and cumbersome. But the game is fun for me, and I'm happy. It has also improved from the time I started playing 1 year back, and one can play like half hour per day and complete all the objectives (mostly). Some of my friends are F2P and after 1 year of playing they have a 4 star mata hanger, but because they don't buy things, they don't have a large pool of mechs, pilots and implants and weapons - legendaries. But they are also happy as they didn't spend anything at all and waited for the events. In an urban lifestyle, playing quick fast paced games like Mech Arena is fun and a much needed mood refresh and the game will probably be alive for years so money is not wasted as it is a great fun and having a good time.
